How can I believe Tim and Savage? Taking Measurements

Incidentally, here is the bolt from the head that goes in the bottom hole surrounding the timing chain cavity. The grey stuff is rubbery RTV type sealant. This is a weak spot- clean off the RTV well, hit it with acetate solvent, add some blue (medium) Permatex locking liquid (Or medium loctite) and reinstall.
















Savage taking measurement.

Protrusion / height of alignment sleeve above head flange surface.

This is the depth that MUST be in the rocker arm assembly, or the pin is too long!









The height of the sleeve above the mating surface of the bolt hole flange is 0.3695"

This means the rocker arm assembly counter bore MUST be 0.3695" or greater in depth.










This is the measurement on the UN modified sleeve, overall length.











This is the depth of the counter bore in the rocker arm assembly. WAY TOO SHALLOW!

THE PIN IS TOO LONG!

File or grind the sleeve down to a final measurement of around 0.465". Remember to put a slight taper on the outside of the pin. This may help center the counter bore of the rocker arm exactly where it should be.
