I'm waiting patiently to see the bowl work in the exhaust side, that set, just like the set I have here, have a very pronounced throat cut, and it's quite abrupt where it stops..
This head was very quiet to start with and with a little shaping had fantastic air speed numbers. I decided last year I wasn’t even going to touch their valve job on the exhaust side. I didn’t want to mess anything up. Lol.
