More to come for sure (including cast iron d-ports)

Tremendous undertaking, thank you for bringing what looks like a nice alternative to market.

Thanks! I'm sure just like Edelbrock there will be improvements made as we go but these should help keep more Pontiac's out there running Pontiac "Injuns".

I share the same sentiment as Lou. Thanks for looking at these in depth!

60539 would be the correct comparison for the bare heads. 60589, are the older style chamber that doesn’t need cnc’d but just polished. But they actually cost more now than the Cnc heart shape chamber. The cnc e’s are 60539 at 72 cc. Which are 870.50 through summit.

I wasn’t trying to poop on anyone’s efforts I just feel like with such an important part it needs a lot of scrutiny before everyone just starts clapping their hands and jumping up and down. I will have almost 10 grand in my engine and I would hate to lose it over 300 bucks

Over the years how many sets of 670's, 16's 48's etc., have been butchered up, blown up, cracked from overheating or freezing, piston kissed, valve sank, well you get the idea!
They ain't making these ever again! If you have a nice set, you might consider putting them away and running these modern replacements. It's time to start saving those original heads for restoration projects. My dragster has 62's on it that are pretty close to maxed out for d-ports at around 260 CFM. These out of the box as cast street heads flow 289/202 CFM at .600 lift and weigh a bunch less (I'll be weighing them later today). Let's help keep the past alive as we move into the future.

Flow numbers would certainly increase but why advertise "street" heads that flow 400 CFM at .900 lift when no one is really going to drive their Pro Stocker back and forth to work. I'm sure we'll do more testing at higher lifts once the CNC ported versions are out. We just wanted to show how these as cast stack up against comparable street heads. Thanks for asking Stan.

Its pretty interesting whats going on with all that. Gone are the days of the small "high velocity port" in modern performance engines. |

Yes this is the street section, but the other section here is race. So there a number of people who full in between. Let call them street/strip cars. I would have thought some of these people might have been interested in the flow @ 0.700" lift. Stan

Companies have to see a ROI and if after investing $250K to bring a product to market, it's simple math. $250K divided by X amount of sales = a profit in how many years? If it's a low volume deal, the price has to be higher to recover the investment. Are there that many boats (not BIG cars, actual boats on the water) running Olds engines that it could justify the low price?

I for one would be interested in flow numbers up to .700" We run our street cars with over .600" rollers in them and drive them everywhere so I'd be particularly interested in .050" increments above that, and see if there is a point where the heads roll over.
