I've been preaching this for a long time, so have a few from ClubGP. Garlocks belong in the trash can, not on your car period. Unless you like replacing S/C gaskets. They oil soak in a minium amount of time and thats with or without RTV on them! They suck, ZZP IMO succesfully made an S/C gasket thats a downgrade to stock. Congrats to them.
I've done 4 installs with Garlocks and RTV on all sides, torqued to specs and all and they oil soak.
Do yourself and your car a huge favor, buy Fel pro or OEM GM gaskets, use a light coating of Red High Temp RTV around all the ports on a both sides, install them, and enjoy properly sealed gaskets. In 7 years I have yet to have a problem with OEM gaskets, much less OEM gaskets and a little RTV. Good luck.
