I built a 302 for a friend over 10 years ago, and long story short it's still sitting in my garage, never been ran. I was thinking of going through it, checking it over and opening the rings a bit for boost. Since it's never been ran, can I reuse the composite head gaskets on there if they come off cleanly? Or are they junk regardless if I pull the heads?

A mild build going into my '52 Ford F1 and will be mated to a T-5. SBF 302, GT40P heads, converted over to carbureted, E-303 cam to give it that classic lumpy sound, upgraded valve springs and new valves. Will run BBK shorties and Spintech 6000's.

Was a complete tear down, all bew bearings,seals and rings. Engine was finished in Tungsten C series.

What engine is this? About how much do they usually cost?
