Yes Ellis we all know about your crazy 18* heads

 

If you take about .050 or so off each side of the intake manifold, it should come down a lot closer... it'll change your port alignment, but I had to take about .065 off mine for the ports to line up correctly anyways, so yours may be the same... stick a mirror and flashlight in the tb opening and see how the ports line up. If the intake ports are higher than the head ports, you are good to go. If they're fairly even, you can't take a whole lot off.

Ditto!

 

The port alignment looked pretty good, so I took my engine-dude up on his offer of a pair of spacers. Whatta pain in the butt job!

I'm thinking I may just pluck the motor back out of there to do the rear holes.

 

Yeah I learned the hard way on that. Had to have the exhaust port totally cut out, rewelded and ported. But the heads do flow nice, 335/245 @ .600 AFR 220's LT1
