I'm trying to figure out if I have a stock head setup or not (I purchased the car about a year ago, and I wasn't given much background on it).

Anyway... its an early '74 260Z. Has twin SU Carbs, and a Datsun Motorsports 3 into 2 header/exhaust setup (its twin exhaust all the way to the tail).

I pulled the carbs/header off a while back to have the header coated and get the carbs rebuilt or set properly... unfortunately I'm now moving in the next month, and I might be driving the Z from VA to Dallas, TX... so I need to get her back together again and running.

The head and the header are square ports. The intake side is circular (not diamond). Is this the "stock" setup for a '74? I'm trying to buy a gasket, and I'm just not sure if its stock or not.

Thanks in advance! I'm sure this is a simple question, but I tried searching, and didn't come up with the answer under "manifold gasket". So alas, here I am.

Thanks!

Sounds stock to me. Intake ports on these cars were always round, and square exhaust ports were used through '76 or so.

go to motorsports and get the thick header gasket , you wont be sorry .

(not exactly the answer he needed beandip) but to answer it correctly, Yes KAZ your head is stock with the round and square ports.motorsport is not the only source on the planet! they do happen to be a bit overpriced sometimes

I've got an extra one here I think I can round up.

The Motorsports Gasket seems to just be for the header... what do I do for the intake? Or is this gasket the same as a stock one, that it is used for both intake and exhaust?? Price wasn't too bad, like $11, and everywhere else I was looking, it was like $15 for an intake/exhaust gasket anyway.

Thanks,

Nevermind... I called Motorsports and talked with them and got my questions answered. I went ahead and ordered from them. =)

Thanks everyone
