What the valve job?

Do you mean a radius cutter vs set angles with a hard edge?

ZL1 if you want to step up to the plate with a setup let me know.

Either way guys might take me a little to get them done but I'm sure they will run hard.

my local engine builder did some stuff to the heads, on the invoice it says

valve job/guides/mill 250$
radius cut 100$

any idea what exactly that means, beyond it just being a "valve job?"

Wrd1972,

yep, that is the valve job I have used for 3 yrs (since late 2004). That is when trevor Johnson starting doing my machine work. I have learned alot from that guy.
