Refurbished Datsun E 31 cylinder head for sale. This cylinder head came off a 1971 240 Z that I recently parted out. It was in very clean condition when I found it, but needed some TLC. This would be an ideal head for your restoration with its clean casting and stock specs. I decided not to modify this head because the cam was in such wonderful condition as well as the valve train. I have listed below what I have checked and had done on this head. I am presenting a cylinder head that you should be able to unbox and bolt to your motor. Stock valve sizes. Pressure checked head. Machine surfaced all three sides of mating surfaces . I measure a total of .018 removed from head thickness. All threads cleaned. All bronze intake seats replaced with steel. All guides within tolerance, new Viton guide seals installed Complete valve job with new intake seats blended to ports. All new valve springs. All wipe patterns checked and any adjustments made. Valve lash is adjusted on all valves. All combustion chambers cleaned of pitting and sharp edges ,and unshrouded for breathing purposes. All Chambers CC’d and all measure 41.8cc plus or minus .2 cc All new exhaust/intake studs installed . New inspection plate. New freeze plug installed Sprocket is used and was just mounted to provide proper spacing for cam. This head never saw a bead blast cabinet and was run thru a parts washer at least 3 times. I am asking 1100$ for the head with credit for your core. Core does not have to be an E-31 casting . Will always consider partial trades for Z parts. . Like I said earlier this should be good to run out of the box . I will ship with a valve cover . Price includes shipping in the USA I will be glad to answer any specific questions and will offer tech support to buyer if needed. PM me or email sfinnerty1018@gmail.com

I would think your compression readings would be a bit higher for that combo. 2.9 block and small chamber head . Those look like stock L28 numbers .

Got to have timing involved in this conversation- period

Okay - good luck

Price, condition, shipping ???

I also agree not to sweat the red engine - kind of goes with the scheme . TB type?

Not being rusted out - I would consider repair . I am assuming that there is no previous repair and there isn’t rust under there. Like said , cut bottoms out and work metal and recap . Take your time and you might not catch anything on fire!

Who makes that intake ? Thought it looked good with the 42 intake on there. Stock engine management?

I have a valve just like that

I did not notice a disparity between my cylinders because of my non tapered box. I think the capacity was enough not to choke air volume to any cylinder .

I will speak on rack boots. All the aftermarket I’ve used did not fit as well as stock Nissan boots. Also lower grade of material. Yes they are 5 times the price , but a bad fit will tear faster.

Wow- that’s terrible - could that even be trimmed up or was it meant to have extra material to be trimmed ?

I think the 37k sell was a bit of a fluke. I think it was the perfect storm of 2 bidders that wanted the car badly. Not saying it wasn’t a clean car, but cloth seat covers :0

Assembly

There’s only one option- the Nissan CAI

It was meant to be

Anything that cuts- torch , plasma cutter , partner saw would be the fastest

Guy powder coats with it .

Yes- makes for a nice heavy stand . Yes - I’ve had one semi successful run and it works pretty well. Need to dial in my technique.

Cut off wheel(ssss) straightening a n47 head in a kiln

Alas - the engine block sacrificed for a worthy cause

I am also very lucky - in many ways- but also the fact that I was able to build myself a Z studio behind my house for my playing time .

That’s just not right Chuck - for one man to have all that ?

Sorry guys - I can’t work that way- I think I’m a bit anal . When it starts to look a little cluttered or I can’t find something - it’s time to clean and organize

Well- not much then. You could sell the rockers if not too bad of shape . Someone might want the stock cam also if it’s in good shape . Springs and stuff aren’t worth much really.
