Chad, can you just clear this one eluded question up, what is the intake runner size?

One more question, how far can you mill the heads down to?

I would be very interested in a stage 3/ with a matched CAM for my M6 06 GTO. CAM must pass emissions. Mods so far are Kooks 1 3/4" with catted mids & LPE CAI. Due to the weight of the car, daily driver status I'm looking for Power under the curve. I'm not interested in a dyno queen. Any recommendations?

TIA!

Why won't these companies reveal intake runner size?

Nice offerings, Chad. Now its open season by the other head tuners! Good Job!!

My concern is using stock rockers on this setup. Any high strength rocker options out there for this head?

The only other option you have for rocker arms is to buy a set of L92 intake rockers (8/offset) and a set of LS1 exhaust rockers (8) and send them to Harland Sharp. That's my plan.

What chamber volumes do you offer? What's the weight of the valves? Have they been milled any and if so, how much?

To have the Harland Sharp mod done to them. Its a popular thing to do for LS1 rockers and since the L92 heads use the same exhaust rockers as the LS1s and share the same characteristics as the intake, other than they're offset, they should be able to do them.

Sure doesn't. Way over priced. I just can't see paying that much money for a set of rocker arms. Too bad T&D don't make a set.

Anybody know if the heads will work well with a 408 with a 244/248 cam with 12cc pistons?

because they are probably in the 300cc arena, with what little is known about a good cam just for these heads in a stock form Im surprised anyone is even porting them but still I bet people are gonna buy em even though everyone is shooting in the dark.
Call me crazy but it seems like people are putting the buggy in front of the horse.
