These are what I'm using
68044 Valve Spring Set
COMP Cams 630-16 Super Valve Locks, 10 Degree/1-Groove, 11/32, Set/32
COMP Cams 740-16 Steel Retainers, 1.437-1.500 Inch, 10 Degree
Everything went together great!
I'll let you know once I get the motor in and running, but so far no spring bind or valve to piston issue in my 5.2 Mag. I put the head on with NO head gasket and used playdough with no valve to piston issues.
Using the Comp 1.6 Chevy Roller tip rockers, Comp guides and 5/16 to 3/8 Stud conversion
