Message clearance? (between lifter and base circle). Their website shows 0.45mm(0.018") for intake and 0.38mm(0.015") for exhaust. This clearance seems to be a lot compare to other solid lifter vehicle. Also, it seems a little strange since intake clearance is more than exhaust.(maybe it's the inconel exhaust valve? Less thermal expansion?)

When I put them together at their spec, it just seems too much clearance :) Of course this doesn't help since I am comparing it to the stock hydraulic one which has 0 clearance:)

Anyway, it's gonna be PITA to get the clearance right. Measuring shims thickness & lifter height to get the right combo for the clearance etc.

Some pics in the progress:

Lifter height:

this save me some time when checking clearance:)
