Need correct casting info 1969 Nova L34

[EZ Nova]

What would be the "correct" heads for my 1969 Nova 396/350 L-34 car. And intake too? I seem to think 215 casting are correct, and what about the intake, 3955287 I believe is correct.

Did GM ever make an alum intake for the oval port heads????

likely the 3931063 oval port heads and no aluminum manifold for oval port in 69. The 3931063 head was used on chevelle 325/350 hp engines for 1969. The intake for a chevelle was the 3931067. i checked my parts manual and it shows two manifolds for the Chevy II (Nova), Chevelle and Camaro and the part numbers are 3957996 exc Sp H/per and 3947084 W/Sp H/per, no mention of casting numbers in the manual.

Yep -- the 063 heads where the first move toward "open chamber" heads. Spark plug side of combustion chamber was opened up a bit. TAZ

Yes...but only for the Corvette...there was a low profile QJ intake for the 390hp 427 and they made an oval port version of the tri-power setup as well.

Thanks Wilma. I knew of the tri-powers and not looking to go that route.

Just thinking out-of-the-box here. My '69 L-34 car is going ZL-1 for the near future. Doing some shuffling to get a '69 Vette for my &quot;052&quot; block ZL-1. Then, since I have basically a L-78 shortblock sitting, and my cars an original oval port car and not a square port car, so doing up a set of 063 for it with an OEM intake.

Have to see what my engine guy thinks? would like the 063 motor to make about 1.5Hp/inch??? He's always telling me that's a walk in the park with a BBc, so let's see. Would try the 427/390 intake and see where we are, but I also have a C396, Holley Strip Dom and Victor 454 oval port too.

It depends when it was built. My L34 C JF motor was final assembled 7/28/69. Block is 3969854. Heads are 3964290. Intake is 3931067. Distributor is 1111498 and carb for a 4 spd is 7029215.

Thanks, Just when I thought I had it all figured out!!! LOL

Original motor is LONG gone, but would still like to keep it somewhat correct.

I do appreciate all the info guys. THANK YOU
