ok, have checked the valve stems and have checked the width of seats, have also checked valve free play but it is so minimal that i could not get the finest feeler guage into the gap for either one (finest feeler gauge i have is 0.015 or 0.04mm) obviously i could not measure the valve guide ID because i do not have the necessary equipment.

VALVE STEM OD IN: 5.425

VALVE STEM OD EX: 5.455

VALVE SEAT WIDTH IN: 1.2

VALVE SEAT WIDTH EX: 1.0

It seems that there's still enough meat in the valve seats to lap away. Should i go ahead and use the guides and valves that i have? (they seem within service limits).
Also, i have read a bit about valve lapping and it makes sense, basically using the valve as a guide to essentially grind away at the valve/seat so they marry well, yes?

PS: Sorry i have notcied ur talking inches, im talking mm, hope it does not bother you. blush
