Option: Tap additional holes in the heads rather than oblonging holes in early intake.
Slots in valley pan gasket show difference in hole locations.

Early intake may sit lower between the heads due to .033 early to late deck height difference.

If heads have been milled .033 then early intake should fit just right on late block.

block has been decked and heads have been shaved found a dual quad intake for an early motor that would be great for my cj thanks for the info
