RHS head valve train geometry issue

Yeah I saw all his little requirements to answer. Lash caps are not just for length discrepancies, they also very handily address diameter issues adding surface area and are a fine fix for valve train geometry issues.

sure....but then u have side loading issues on the guide, increasing the contact area yet leaving it offset ..is not the answer.

the stems could be cut down...but he might find by the time he is done ..that the tips recede below the locks.lol

'usually' if its too far to the exh side...the stems are too long.
