T/A HEADS AND ROCKERS!?

[BWP340]

that casting number was used n standard 4360 and 340 heads as well.
It came with 202 intake valves and a smaller combustion chamber than the others.
It is only a T/A head if it says T/A on it.

That's incorrect

His heads are definitely TA heads as the non TA pushrod indent is on his heads. See circle below. Thinking more about it, this 360 could be built up with those heads and more gas pump friendly compression pistons and ~.500" lift camshaft and last basically forever without ever blowing a head gasket!

Yeah I'm trying to decide what I want to do. I could build it but I would want to be conservative with it. My trans and rear end are stout but I would have to really beef up the car to handle a lot of power. 360 block and heads may should stay together

Nice. Ta heads. One J and one U. I had read mismatched was not uncommon

Ball park guess, the 360 with those heads, a .500" lift cam and 9.5:1 pistons (measured) would make about 360 HP and 400 ft-lbs of torque assuming everything was dialed in to work together.

Yes, I agree, the block and heads should stay together since the work done is common to both.
