Re: dart to GM head test
I've heard you'll find water on the darts in places you won't on the gm's.

Are those #'s from Dart? I believe their p/n's have 8 digits. Dave |

Re: dart to GM head test
What the heck am I missing.. I saw another post on the other forum about Zavala running a 'replacement' 441 head..... So we now have NHRA accepted aftermarket 255 SBC heads for SS ???? Where is this posted ?? I just checked the latest "NHRA accepted products" list and there is nothing listed ??????

Just go to the NHRA Classification Guide and look up 1969 Chevrolet 350/255 hp.... You will also pay with 5HP for the honor of running Dart, RHS or World heads.... Bob
