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

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.

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.
