Xr7g428,
I wasn’t really excited about spending the money on so aluminum heads so I started looking really close at the heads that came with this engine. I was a little disappointed to discover that the air induction ports are actually drilled! This makes them useless without an air pump system to my knowledge. So the engine build is on hold until I can find new heads or save the cash for aftermarkets. On a military retirement it could be awhile 
Thanks for your input
Cheers
