im about to do a head gasket change on my 5.3L.
got a weeping pass. side gasket and its time to pull them.
Would you guys recommend the Cometic (spellcheck) or the factory GM?
ive been getting conflicting stories.
While im here, i will be adding the FAST 102MM cathedral port intake and 92mm throttle body as well as ARP head bolts. (daddy's gotta get something out of all this effort!!)
Let me know what you think gentleman.
