Bronze guides

alloy might be different.

Throw in Del West USA also for Bronze valve guides.

 

[agm]

just get any bronze guides.

any machine shop around you should have some. check into cost there. i would skip those JUN ones and go with ferrea or supertech if youre going with some online ordered ones.

just make sure you get the right size.

if you get a material other than bronze, the valves themselves will likely have an affinity for the metal in the guides and it will cause premature wear.

I have information. .0015" on the intake and .0015-.002" on the exhaust is perfect for the
bronze guides.
