BTW that is a pile of iron to move on a W2 intake port, looks good, now you have to finish the other 7.... 1 port is always fun to do, it's the last 7 that suck
They should run real well, I really like that 47 CC chamber in those heads, excellent shape to it & depth. The 55 & 65 CC Closed chamber 18* stuff is an OK chamber shape but way too DEEP, the 47 is real nice depth & overall shape, much better on the plug side wall than the 18* stuff.
