Scott, I had a similar post last week and someone said that the 190cc heads would not be enough for a 351W. What are your thoughts on this? I'm not stroked, just a .030 over 351 with GT40 upper and lower and 30lb. injectors. I'm intrested in the ProComp heads also. Either the 190cc or 200cc. Mike
i had a bad experiance with them, guess i'm just the lucky s.o.b that got the set of junk castings . oh-well some other guys said they have had good luck. go figure, i'm the pro engine builder and i get the set that won't even cool on the dyno. procomp did tell me that they would exchange them no problem, that was refreshing news. the 190s are about the right size for you 351, but imo, the are still not as good as AFR 185s. life is full of comprimises.
i am VERY happy for you Scott. i would like to give the procomps another try, just alittle gun shy. i have had great luck with their steel roller rockers. i'll probably be a procomp dealer in a few weeks.
