when i boght the gsr head the dude told me that his timing belt slipped on the dyno.
and i found out later that he didnt replace all bent valves
because some of them were hard to pull ot of the valve guides.

i bought new set of valves and new set of valve seals.

but in case like this ( or any other bent valve case)
do the guides get damaged or is it ok to use them?

 

should be ok. but you can measure the valve deflection, If I remember correctly, with the valve off the seat 10mm, the max you should have is .009" to .010"

 

need special tools for that right?


what would be the consequances of having too much play?

 

I use a dial indicator set up so it comes in on the side of the valve head. Bads, unstable valve, and leaking.
