Ok I'm trying to set stock pedistol rockers and tourqe but when I turned wrench I'm getting different amount of turns with my wrench. I had a mechanic come install them and he said the heads were milled different and uneven.On the same head getting different readings on both sides of the same head.Also noticed the vavles stems area different hights.Put a straight edge across the top of vavles stems and some are shorter then other.I just bought remanufactured heads at machine shop and assumed they were fine. My mechanc recommended me have them remilled so that they are the same but I feel one of them has been milled short cuz it takes 1 full turn to full turn + quarter turn on some and The other head takes quarter turn to half turn to tighten rocker studs.So he said the head that takes full turn is the one that has been milled more short.He recommended me take them to get remilled but I feel if I mill the short one to make it even then it's going to have to much compression.He said I could get a thiker gasket for that side I'm using felpro blue stripe I believe so I might need one thiker then that,so I was wondering If the vavles stems might be the issue? Do they need to be the same height across? Could that be a reason I'm getting different amount readings on tourqe wrench?Any advise guys?I never even thought that the heads could be milled uneven.
