building a 408, now do i run my prc ls6 heads or l92 heads?
decided iam building a CARBURATED 408, sold my 347 to my buddy, now cant decide what head to run, i currently have prc ls6 2.5 heads with manley valves,prc gold springs, and jesel rocker shafts, now would it be worth it to get l92/ls3 style heads? and a carb intake like a edelbrock victor jr? how much power would i really see? the car is a full drag car now will mostly see the track with minimum street use, also will be shooting for 12-13to1 compression, any help is appciated thanks..

Hands down the L92's
You'll definitely gain more especially if they're ported. Go with a reputable sponsor such as AI or WCCH.
They'll even spec you a cam, assemble your heads and possibly port your carb manifold with a portmatch job.
