Thanks so far guys if i used 3.0 heads would it not lower the C/R more(hmm turbo thoughts) from 9.7:1, and why are other owners using 2.5 svt heads with 3.0 valves. i take it there would be no fitting problems, i thought that the 3.0 had mor agressive exhaust cam than the svt?( anyone got a set late of 3.0 heads with waterpump drive for sale)
