Had a nice box on my doorstep today My ported L92 heads came in.
From Texas Speed and Performance. Its fully CNC 5-angle valve job. The machine that does this is brand new and there are only 3 in the country right now. Oh, and these are fully assembled heads too.

Here are the flow numbers they sent me for the heads:

<<Here's some flow data from the stock valve port:

.200 153 113
.300 223 151
.400 283 185
.500 320 204
.600 346 225
.650 350 230

Here's some pics

 

Great looking pair of heads.

 

Nice.
I am keeping mine stock..they still flow outstanding numbers from the Factory..beat most of the AFR's.

 

Nice ! Good shot with the water bottle . What are size valves ?

 

2.16" & 1.59" valves

 

Stock..are they Manley Stainless? Or are they something from TSP..

Those are some damn good numbers too. Mine right now get 325/210 @4.000 Bore, .600" lift. That's Stock.

 

is what stock?

 

They are Stock size Valves..who makes them..

oh yeah, the valves are stock. I discussed 3 different valve options with TSP and for my particular motor plans, the stock valves were the best choice.

 

those will look pretty on my GTO's LS2
