S14 sr20dET.Head was given some love by a local shop where they;Put new valve guides new stem seals and they reseated valves.Now when I am puttin the cams on, I have no clearance! Meaning I cant fit a feeler gauge at all between the cam (Lobe pointing up) and the rocker arm. SO its always touching! My first reaction is..."if they cut a smidge off the valveseat, and a smidge off the valve to match...then I am off 2 smidges. But what do i do?"1) Have the valve stems shaved?2) Have the rocker arm feet shaved?3) have the roceker arm pad shaved?Any help is appreciated.Thanks guys

stock cams I assume? What does the shop say about this? seems like they would have a fair amount of experience in this dept.

HLA'S...I read your great article on the 9000 rpm head and in there you say that there is a clearance of .155mm between the cam and the rocker. Yet I cant find those clearances on my FSM.
