Question What Are These GTP Heads Worth?

I have a set of GTP stage 2 806 casting heads that i need some advise on
( 97-98 heads ) None center bolt valve covers
they flow

intake
100 200 300 400 500 600 700
65 139 192 230 256 275 284
exhaust
100 200 300 400 500 600 700
56 109 151 179 198 210 218

66 cc chamber

They have a fresh valve job, all new seals, 918 springs, and are ready to bolt on.

What do you guys think they are worth?

806 castings? are they center bolt valve covers? I would say not a lot considering the price drop in the 243 casting ls6 heads. You can get a new set of CNC'd ls6 heads for under a grand. TSP even had a specail with some old CNC program ones for $795. Used ones are going in the $600 range on the board.

Above response is right, those flow numbers are more along the lines of stage 1 numbers.

Oh yeah, non-center bolt valve covers = Paper weights. Sory.

I think stock 243 castings flow that good or better and can be had for $300 on the board, $500 with new 918 springs.

GTP does some good work. Those sound like older, ported heads.
