Do you have aftermarket heads that require round ports or stock Pontiac round ports? I'm wondering if the E heads have the exhaust port surface at a slightly different angle than stock Pontiac heads. Do you have stock engine and tranny mounts or aftermarket ones that could be thinner of thicker than stock?
I have E head round ports and using aftermarket Trans mount and have the Butler Poly mounts. I attached some pics that were kind of hard to get the right angles with most everything install so sorry up front if they are kind of crappy. I can tell you that my engine does not appear to sit any higher then before. I do have solid body mounts or aluminum, which ever they are.
