I have an mid 70's block etc but I have 1986 5.0 Litre heads on it. I need to upgrade the pushrods as the newer heads have bolts for the rockers not studs like the older ones. Anybody use the comp cams pushrods and rockers?
I am using the Crane/Ford Racing 1.7 roller rockers (pt# F3ZE-6529-AB) and Comp pushrods on GT40 heads with good results. These are on a 5.0 block converted to accept a roller cam and lifters. They look like this...probably similar to the Comps???
Or, if you're not gonna race the car, you can get a kit that converts the pedistal heads to studs. http://store.summitracing.com/partdetail.asp?part=CRN-36655-16&autoview=sku
