Hey Kev I hear that Woody's in Thorntown is "THE" machine shop to go to around here for bada$$ Ford motors. I don't have the number right now but can get it for you, it would be a really good idea to call him and see what all he reccomends. BTW as far as your current problem goes everyone I have talked to thinks we need to re-check the valve pre-load...
Talk to you later!
