I have a set of 69 351W heads going on a 93 302. Besides stud mount rockers, what else has to be changed? Are the pushrods the same length? Any help is appreciated.
I learned just the opposite, with regards to potential. The GT-40 iron that came out way back when, was a 351W, with big improvements in airflow...but im not a head porter.Wow, GTp heads or 69 windsor heads. new headers or new rockers. the windsors have much better potential and are a high performance peice compared to the GTp's. swappin these heads are worth some good power. Installin is no different that any aftermarket head. I dont even use the bushing on my heads but Im using ARP studs.
