1> Nope. Intakes are 2 groove, exh is 4 grrove IIRC. You can buy performance aftermarket stock replacement locks for them tho
2> You can go further. But you end up creating issues that are more costly to adress - i.e. milling the intake flange side of the heads, sometimes intake itself, valve cover and intake fitment, and pushrod lengths.

my comp spring kit has 626-16 locks says (These Chrysler four groove Steel Super Locks™ feature a 10° lock angle and 3/8" valve stem size. They are recommended for all race applications because Super Locks™ have a wider angle (10°) that better distributes the ever increasing valve spring loads over the retainer than typical 7° locks. Precision-machined out of super-tough, fatigue-resistant metal alloy, Super Locks™ fit any COMP Cams® 10° retainer) are these correct?
