from what I havce found on this, the older heads will work with the EFI intakes after opening the ports on the head some, apparently the ports sit lower on the carbed heads...that makes the carb intakes unusable with EFI heads, though, from what I have found on the net
honestly, at this point I'm looking more for some suggestions on what cam to use that is compatible with the speed density sytem
D3's have the bolt down non adjustable rockers. The other information is correct.
