well them heads need a bit of work they are 420 cc intake runners and flow ok .i think they will work i have a cam that i have work on for this engine .if i put them on i will go back to 13to1 cr i do not drive the car much and run race gas in it any way so 1000hp and 800qt or so will get the job done
i may not use the heads . a lot of this stuff was for a customer and he back out on the deal so i was thinking of putting them on my car , i need to keep the stock gto hood i like it. and i do not like glass hoods so i not sure if i cut the front cross out i may get 1 inch that will not help and the are cleaner is working on the inside of the hood and the oil pan is on the front cross that is cut and box for the oil pan . i do not need any more power just want to see if i can do it

Good looking set of heads Pat..... They should be just about as economical as the Super Cobra Jet heads I have out in the garage!!!! Only time that engine got any kind of decent fuel mileage going down the highway was when the car was in the trailer!!!!!!Yesterday is history, tomorrow is a mystery, Live for Today!

You're welcome Mike, glad it worked out for you. Roger, it's taken a few years but my inventory of excess parts has shrunk a fair bit from 1 1/2 garage stalls to about an eight by eight space. ...
