All,
Considering a valvetrain kit for my 340 gas. It appears the major benefit is to renew the valvestem to valveguide clearances in my thinking.
Do the guides require reaming to size after insertion or are these head in the oven, guide in the freezer and arbor press to depth?
Other than taking the head to an engine machine shop for valve seat grind what else am I missing ?
My experience on other engines says the springs, caps and keys aren't problematic unless they actually break...as long as the springs are and as slow as these engines run I can't see a lot of issues...
Thanks for any advice.
