CFM?

Intake runner volume?

Could you just swap everything from your stock heads over to these? (aside from likely upgrading the springs for a cam)

Katech_Zach

Yes, you would just swap over your valves and springs unless you are changing the springs due to the cam.

We don't advertise flow numbers. It's all a game that we just don't want to play. We've seen heads that flow less and make more power. We've also tested competitors heads that don't flow as advertised. These make power and are sized for mild to moderate camshafts and superchargers.

Thanks for the reply. I'm not so sure calling other companies liars and not providing any numbers to back up your heads is a great marketing strategy, but hey it's not my company.

Katech_Zach

I never called any company a liar. Never would. Just saying we did our own market research and the results didn't match claims.

Good price for no core charge.

I guess I'm just saying it doesn't look good that you can check the flow numbers of other companies heads but won't publish your own.

I would think customers would want dyno numbers or flow numbers or something. I know I wouldn't buy heads without something to back up what I was paying for.

Katech_Zach

We never said we wouldn't share dyno numbers. We picked up 12rwhp on a mild cam LT1 with just the head swap. There will be more with bigger engines and more aggressive camshafts.
