I was just curious what is the big deal on the L92 heads that scoggin Dickies sales..They have sets that arent cnc'd for 500 each or that have been cnc'd for like 600ea. Whats the big deal? What part is CNC'd?chambers? Is it worth the extra $$??Thanks

We've flow tested those heads as well as the prc l92 heads next to each other. Both sell for about 1000-1100 for the pair fully cnc ported. Our PRC L92 heads gained 25rwhp over a stock l92 head on our dyno test engine! Pay a couple hundred extra bucks & get the prc cnc ported heads, you'll get better p/v, better air flow, & better power than the stock l92 head!
What are you thinking about installing this thing on?

Thanks guys..Just was really looking at if the scoggin dickies heads were really worth getting the cnc version.. I'm really open for any cylinder head company..as long as the price is right and there good head.

I have a set of Richards heads on mine and it makes good power to 6500 rpm. They look like a work of art. ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
We are putting the higher rev range down to increased exhaust flow. I don't think we have nailed it with the right cam yet.
cheers

You might search under my user name on l92 heads, we have tons of dyno data from engine dyno testing. We've produced past the 560rwhp mark with a m6 f-body running our l92 heads on a 418! I've even installed l92 ported heads on my stock cam a6 vette that made over 400rwhp with no cam!

Nice graph. Looks like things are leveling out around 6K, which is fine for my application.
did anyone say if its worth the extra $800 bucks for the CNC, I know for max out it is but for a DD, ocasional track guy??? Or even more so for the budget limited guy

Has anyone read the GMHP article where Golen built a 402 w/ L92 heads? Close to 600hp.
Golen did their own work on the heads. Here's the link.

Enjoy.

Sorry to steal your thunder. They sell GMPP's CNC L92 heads more often than they sell the PRC's. But they can get anyone interested in the PRC heads setup too!
