Thanks Dwayne, I think changing springs to the comp 26918 or the Manley 221428 is the best option

Jeremiah, I hadn’t checked other suppliers, thanks for that suggestion but still turned up with no +.100 options. I checked comp, Manley and PAC.

Wastedays, you have to run a shim btw the mic and the retainer when using the small beehive retainer and standard Mic. I use .060 shim because that is the thickness of the spring cup/locator so 1.720” is the actual install height.

Pittsburghracer, just trying to make the heads, valves, springs, retainers and locks I was provided work with a .563 lift cam.

Thanks to everyone that offered help and suggestions.
