5.3 heads on 408?
5.3 heads on 408? Ive done a few searches and havnet realyl found much out..
Ive got (what im told are) GTP stage 2 LS1 heads
Ive also got some 5.3 heads that appear to be CNC ported(im going to flow them both this week)
Going on an ~11.8:1cr 408 with a TSP 231/237 cam, ported fast 92.
I will choose head gaskets accordingly to keep my cr around that point, so which heads would be the better set? whichever flows better?
