so whats the difference in GT40 and GT40P heads?
and now i see a GT40X or something...but at $600 EACH...i dont see those in my future....the GT40's seem to be about the only head ill find used and not cost a fortune.
also since we already talking about me being poor....is there a decent "budget block" that can handle 400+ rwhp? without breaking like stock 5.0......obviously i dont have 2k to put into a block.
