Did I hear my name mentioned?
Clevelands here were used here from 1970 until around 1984 in both 302 and 351.
It's the closed chamber 302 heads which are the ones to get. The combustion chambers are slightly smaller than the closed chamber 4Vs, and will boost the compression ratio to over 11:1 with flat top pistons. 351 heads were either closed or open chamber 4Vs, and open chamber 2Vs. Make sure you get the 302 2Vs with the closed chambers!
As for the intake manifolds, we had 4 barrels on the 351 4Vs, while all the rest were 2 barrels until around 1977, when both the 302 and 351 went to 4 barrel Carters on Spreadbore manifolds.
So what to get?
302 closed chamber heads with 4V valves.
Aftermarket alum intake manifold.
I had a friend who basically had the same combination as mine, but he had 2V heads and I had 4Vs, and our 1/4 mile times were almost identicle. And he had more bottom end torque because we all know that 4Vs work better up in the higher revs, so it was he who got me off the line!
So having said all that, these things are getting harder to get over here these days. They are still around, but not as cheap as they used to be.
Your best bet would be to source them from a US distributer. There are a few around.
And we all know how heavy cast iron heads are, so freight would be the killer.
