Tech Question
Tom Butler, Hollidaysburg, PA , 1978 Dodge Aspen 360
I have a questions about heads for my 360. I currently has a set of J heads on the motor, but the heads are starting to get a little tired. I was wondering about a set of 308 heads and I believe that I found a set in a '89 van, but I can't see the casting number to be sure or not. Did these heads come in vans as well as trucks? I also have a set of E-58 heads from a cop car engine. Should I save myself some trouble and freshen up the J heads, or should I go for the other heads. Thanks for the help and the great tech articles!
Tom-
Yes, B-vans were trucks too, and we all bemoan their sad fate at the hands of Stuttgart.
The 308s you found are very, very similar to the J's on the intake side, and quite a bit better on the exhaust - virtually as good as W-2s! Plus, the exhaust seats are induction hardened, saving another expense and hassle. So there's no question which heads to use. The mid/late 70s smallblock production heads - ALL of 'em - were pretty sad pieces.
