In the process of picking heads for a new 355 sbc with 10.5:1 compression, Comp cams High Energy 268h. I'm currently trying to decide between Edelbrock Performer RPM PN: 60735 or ATK PN: sbc70185. Any advice would be greatly appreciated.
ProFiler only has the one SBC casting line-up, the "All-American".....for some reason you keep alluding to this being an import casting. It's not......Notice chad uses the american profiler for his port work not the "all american" cheaper castings. ...
