Studs installed, will be putting thread sealer on them and torquing. Measured valve seal for proper replacements, even though these seals looked perfect. I ordered up new seals, springs and locks from alex's parts. Springs are good up to .550 lift and have proper pressure for roller cam. New spring on right, vortec spring on left. Oh they come with shorter retainers, which with vortecs you can use stock retainer and "ghetto grind" them to save some money. biggest problem with stock vortec heads are the weak springs and retainer to valve seal clearance. there are lots of ways to go about increasing your cam lift, I took a quick easy way for this drop in setup that is meant for vortecs.

Bores were glazed, so I gave them a light hone.
