what do you guys think about these heads on a 454 mark lV base motor it has stock stroke and .30 over now but plans for future are .100 over 4.250 stroke and 11.00 to 1 comp and roller cam . my question is will they work on this or are they to big , the price is right thats why I'm asking

A better place to post the question would be in the dyno section. You need smaller heads in the 310 cc range with a 454. Good heads are not rated by the cc intake and exhaust as much by the port velocity and other stuff that everyone is an expert in on the dyno forum. ASK for Bob, their always seems to be a guy named BOB there or A Scott guy. Both work with oldsmobile, chev and ford. I think :D
