I didn't realize it till after I had both heads torqued down and I was about to check my pushrod length, but one of my intake and exhaust valve stems were worn pretty bad on the used heads I bought. Looks like the guy I bought them from had a a couple loose rocker arms that were bouncing around and beat the contact surface up.
I'm willing to buy a whole set, but would rather just replace the two that are bad. Please let me know what you have. I need these ASAP
Thanks.
