BEFORE u ask about the knurl v replaced guide:

Place valves in the head. Get the assembly outside into DIRECT SUNLITE. Move each valve up and down and rotate valve a little bit. Look for any sunlite that may pass thru the seat. THere should be NO sunlite passing thru. Mite have to force the valve head against seat with 1 or 2 pounds of thumb pressure ok. Rotate valve checjing for sunlite. There mite be one or two points of rotation where a very tiny fraction of sunlite appears and that is ok if it is a very tiny amount.

There should be at least one point (of valve rotation)where NO sunlite is evident with just 1 or 2 pounds of thumb pressure. Key up valve at that point.

If there is any point where excessive sunlite passes thru then it will create less than desireable compression.

If it passes the sunlite test. Then key up the valves with springs for final assembly and LEAK TEST OVERNITE with kerozene. Some very slight moisture at the seat is ok but there should be NO puddles on the ground.
