I pulled the motor out of my 67 and removed the heads I knew were 65 hipo's and had roller rockers with double valve springs. what else I found was impressive to say the least. The first thing I noticed was 2 inch intake valve and 1 21/2 exahaust this is measering accross the face of the valve. I compared to my lt7e heads I was going to put on this engine and the valves are huge in comparison. I also started looking at my ports and they to are very much bigger. Some one has spent the time on these heads. The only bad thing is the car didn't idle well and it had a c6 with a stock converrtor. I am changin to a AOD and will be replacing the cam. My question is would a mid range cam with like 230 duration and a 2000 2500 stall work well with these heads. Also the 65 heads are 53 cc chamber correct? well the 71 mexican 302 has flat top fly cut 30 over pistons. Just from what i know this set up would/should have around 11 5.1 or higher compression. I also have a stock 89 5.0 I was brain storming a bit and was wondering if I can use my crank from my 71 as well as the rods and get some dish piston or stock roller piston and use the hipo heads to make me a 28oz roller with about 10 5 .1 compression. will this work and how much do you think I can sale the mex block and fly cut 30 over piston for uised?
