I bought my 1st Z, '76 280 in 1987 for $1,000 because it would only idle. Trailered it to a mechanic that popped that cover off and tapped that sweeper vane loose from being stuck because it sat for awhile. Ran like new.

I talked with my machinist Monday morning about the bronze valve seats. What a relief when he said he had a seat machine and thinks he still has some steel seats, both sides too for Nissan heads $5 each. So a little more grinding then it's his. My header and 2.5" exhaust came in too. MSA is still putting their 6 into 1 header in a shoebox and kicking them to my house, it was sticking out really bad but they got lucky. I went over it last night with a flashlight and found 1 ding but I'm okay with it, $503 for both items. Free shipping and 10% classiczcars discount. Broke out my 280 this weekend, I'd forgotten how good fuel injection is when it's right.

Would the fuel injector holes on the N42 head have to be welded up or is that not too important if the intake manifold covers them? Curious.

Cold for me too, then another quick "fits or doesn't fit" when hot. But I don't remember readjusting a single valve when hot. Is there some other way to find "Kammy's World Famous Valve Adjustment"? I tried linking it for someone on here awhile back and it was gone.

So now Canadians DO get it? Who in their right mind would argue with him?

You're most welcome. After comparing the short Fords to the stock Felpros I think they'll be fantastic for our cars. I ruined a brand new set just trying to remove them, they fit that tight onto the valve guides. When I pulled the valves through them they made a "pop" sound.

I'm not planning on cutting any off the bottom unless it's not straight. I am being careful not to cut much, just trying to blend everything together. Am I making a big mess? I got the P79 down for comparison and ended up spending the day cleaning up my garage. It was 60 degrees and sunny, I needed that.

Ring size is close to what I need. Maybe I can find some moly rings for a Chevy.

I'm on the side of "do it". I bought that Tom Monroe book, read it about 3 times then rebuilt my 1st car motor all by myself and it turned out perfect. One of the best feelings I've ever had, although there was a lot of anxiety and "while I'm this far why not do this...". I could have easily done a good job for under $1,000 but I bought a new exhaust and header and a few other "while I'm this far why not do this...". If you'll post some pictures you will get a lot more info/opinions. Cliff

I've got them on order from advance. I'm using my phone now so give me a minute and I'll post it.

I haven't seen anything that looks like a date code. It's an E31 that came with the tomato colored 240. Triple webers aluminum flywheel f54 bored thirty over with new dished itm pitons. He was following datsungarge.com to the letter. Needed money so now it's mine. Had to do something with it.

I used a scribe to scratch the outline of the HG. You can see it, barely. Do you think soda blasting the bare head would be okay? I'd like to clean the outside, not getting near the combustion chambers. Thanks Steve.

I figured that would be the answer to my question, thank you both. So that means the head has had the bigger valves for awhile. The intake seats do have a little magnetic pull though but nothing like the exhaust side. I guess beryllium bronze has enough tin in it to attract the magnet. Oh well, at least the steel seats are cheap but my machinist is gonna get sick of me quick. I've been smoothing all the sharp edges in the combustion chambers and I tried my hand at unshrouding the valves. Am I trashing an E31? I sure hope not.

Judging by the furniture I thought for sure it was in pristine condition, I was wrong.

I was thinking you had red interior. I looked through your gallery this morning and saw that it is black. That above picture is very tricky to my eyes, it looks like a red headliner and that is all I could focus on. Didn't pay one bit of attention to the seat's head rest.

Blue had the best idea for cleaning valves to me, chuck them into a drill. Low speed with a Scotch Brite pad and some cheap WD-40 knock off. Shines up like new. I did a few last night. I'm working on a head that's been sitting under my bed for 3 years, they have a varnish like crud around the sealing edges. Agreed! very satisfying process.

I knew those were there for a reason. When I put my header on I had to trim around the middle runners to get it to fit, glad I did.

I decided to take apart my E31 before I give it to the machinest, trying to save him some time. Well there was a couple of surprises. It looks like someone has already ground the area around the valve guides and they are steel, checked with a magnet. The intake valve seats are brass and the exhaust are steel. It had the shorter Ford valve seals which I ruined when I removed them, I'll get a new set. I've got a Felpro beside the Viton for height comparison. Should I get steel intake seats or leave the brass? I'm not going to the racetrack and when I run it up it'll only be quick and short. The police know me and where I live with my orange 240, small town. Thanks for any advice, Cliff.

That's a beautiful car you have there. I really like that color combination, reminds me of a late 60s 911 my uncle had when I was a kid (younger).

Maybe snugging the head bolts up would help until you're ready for pulling the head off? When I tore down my 2.4 a couple of weeks ago I was amazed at the difference in effort to remove some of them.

Funny thing about that is my Dad showed me that when I was a kid in the '70s. He was working in the yard and stirred up some yellow jackets that lived underground. They wore him out in about 30 seconds. A couple of hours later he got his revenge. That hole burned like JFKs Eternal Flame.

Okay, I'll rephrase. If I can take some measurements for you let me know. I have the OE '72 radiator hanging on a nail in my garage. I've installed the larger 280 radiator in my 240. Fits great although it's 2" lower to the ground but still not as low as my front spoiler.
