... and is it worth it?
I think I'm going to rebuild the whole thing at this point, have to regrind a valve and replace 2 rocker arms and a rocker shaft so it's pretty much got to come all the way apart.
I've heard of gas-filled valves, stelite (?) tips, racing springs, 57-angle valve grinds...
Does anyone have experience with building up a non-stock head and does it really matter? Is BMW stock close to hot-rot or will there be more power with more expensive parts?
I don't plan on RPMs above 6500 or so.
THANKS!!! Appreciate the comments.
