One for Julio ...

Julio, for the cylinder heads. We looked at this today and the 1.75 spring height for the beehive springs should work out fine.

We also like to use the comp cam spring locators (hardened steel alloy seat) to make sure to protect the head and also locate the springs correctly. This instead of just using a thin steel shim for the spring to sit on.

The thickness of these locators are 0.060"

Question is how much can we mill the spring seats on the TTA OEM heads safely without any risk to hit water?

I asked Tom at Champion and he doesnt recommend any milling into the heads. As long as you dont get into coil bind, you'll be fine.

Dont worry about the seat pressure.. the roller wont have a problem.

Thanks Julio, appreciate that. We'll mock it up as is without touching the heads and see where we end up height wise and make sure there's no coil bind.
