I appreciate all the replies by the number of replies it seems a lot of people have had the same problem. Yes Tom tall valve covers are an option but since this is an AC car and it has a large PB booster it's not practical for this car. The valve train geometry has been checked and proper push rods have been installed. It's a mild hyd roller with Scorpion 1.65's and lift is .600 and the valves have been adjusted with 3/4 turn preload.
Current poly locks are 1.055 tall
Current studs are 1.915
Set screws are .300 below the top of the poly lock
Poly locks are engaged 7 turns with valve adjusted (3/4 turn preload)
Top of Poly lock is .400 above top of rocker arm at the pivot point
The Crower poly locks are .875 and that reduces my interference by .180. So maybe that plus 5/16 gasket will get me the clearance I need without messing with the studs.
