Late 80's swirl port heads 302/714's
That is my least favorite chamber. Ever. I know guys drool over that thing but I detest it. Reverse flow it once and you'd hate it too.
That's the same basic chamber the W5 had. That was mistake number 1 on that head. I had $150.00 a month phone bills to Chrysler calling them about the crap that was wrong with that head. Like why are the valve pockets so F'ing deep? Why are the seats A) **** materiel and B) why are they so thin? And C) why are you using and oddball O.D. on the guides???
That's a few of many complaints I had. And it starts with that horrendous chamber.
