Anyone using this head? If so, how did standard 4V headers fit (or not fit). Second question; anyone used them and have build information and dyno numbers? Thanks Chuck

I have these heads with Hooker 6915 ceramic coated 4V headers and they fit great.  Only issue is that the collectors are angled inward so the exhaust system needs some extra work to connect to the headers.

Thanks for the reply Scott. What intake manifold are you using? Chuck

1971 Mach 1 - "Day 2" restoration; 351C/FMX, trick flow heads, roller cam conversion, CAA AC kit, upgraded springs/shocks & close-ratio steering box
I'm also running the Trick Flow Heads - no 4V header fit issues at all. My build is relatively mild, and I wanted smaller intake ports with a dual plan, so used the Edelbrock 2665 intake. I didn't dyno it, not really interested in numbers as much as how it feels when I drive it (I've seen some BS dyno results before). With my cam, it's got a nice off-idle response, plenty of torque.
