TSP 5.3 Stage 2.5 or AFR 205cc 66c Heads? I am modding my Z28 obviously and I already have the basic boltons and want to know if the addition of the TSP 5.3 Stage 2.5 Heads are better for the price or are the AFR with the casting and expensive price tag worth the extra $$. My friend says the $$$ you spend on them = the better the overall build. Is one more reliable and should be looked at more for my basic street application with a TR 224/224 .563/.563 114lsa camshaft? Thanks for the advice in advance.
