yep they are the same and they work with the stock pistons!
1. Yes.1.Are these 1.7 roller rockers the exact same? A.Summit Racing (CRN-44746-16 ). B. ROLLER ROCKER ARM | Part Details for M-6564-A50* | Ford Racing Performance Parts (M-6564-A50* )
2.Will these roller rocker fit on thes AFR 165 heads? AFR 165cc SBF Street Cylinder Head Part # 1472. (165cc Street Heads, Pedestal, 60cc 1472*)
3. Will the stock valve covers fit correctly with the roller rockers on the AFR head?
4.1993 5.0 mustang with stock cam and block running the AFR 165 head and 1.7 Pedestal roller rockers (instead of the stock rockers) with the increased lift be a problem clearing the stock pistons?.
