GT40 to Z304 heads
Cannot seem to find a definitive answer. Exhaust ports between the GT-40 heads and Z304 heads. Same height? The Z304 heads are advertised as raised. Not sure if the GT-40 were that way as well? Just concerned about header/pipe exit if I do the swap on a FMS 392 in a Superformance.
