Vortec Heads Upgrade
I paired this with:Competition Cams 787-16 Steel RetainersGM Parts 12499224 Valve SpringCompetition Cams 648-16 7 degree Race locksRemoved stock springs and retainers off my Vortec heads and added these for more lift between the valve stem seal and spring retainer. I have about .505-,520 lift with this combo and I could get a little more by changing the valve stem seals. The valve springs fit with no machine work and are much nicer than the original springs when it comes to coil bind. Cheap upgrades for more lift capability. Perfect for pairing with 1.6 rockers.

Bs not any different from factory gm locks same degree
These locks should be placed lower then the factory gm locks hence the 7 degree and it should clear 30 to 50. Thousands these don’t make a difference

Pure Junk
Had one snap in two vertically during initial assembly. 45 years of engine building and seeing a failure like this is a first. Never again Comp Cams.

Brittle
Broke one upon installation, seems like very brittle material. Can't get myself to trust the rest to be reliable. Returning for refund and going with forged Howard branded locks
