I didn’t know they have a website separate from Facebook. I am not on Facebook, and I couldn’t open their Facebook since I am not on there.
here is a link to their website, for others who don’t want to be trolled:
https://www.performancedrivendesign.com
Looks like the heads start at $10,500, and that doesn’t say what all is included or done to the heads.
Really nice stuff from him in general. If I had the funds, I would do the heads on a Rocket block.

there is such a thing as too big of a port and valve for an engine. Those heads on a 400” short stroke or a big 540” big block would be different. Min CSA and max intake valve size is critical…even though many experts on here don’t know what that even means. Air speed through the intake port needs to be right for the cyl volume and rpm..if it , it could be lazy , peaky..or be a dud all together
the reason you see flow numbers for Edelbrock and Speedmasters is because they are usually low on flow #s even after a max port when installed on a big block…they need to be blasted out so the engine doesn’t fall on its face up top.

the heads would be designed for your specific app. So wanting to know what they flow or anything else would need your engine details and power goals

yessir…sounds like they are fully custom and optimized for each build, which makes them really even more impressive.
I do know a wee bit about that max intake valve size to CSA ratio, but I do appreciate your info and sharing.
Yep, getting these weezy-azz Olds factory port location heads above 300cfm takes a lot….
Even the Battens don’t usually go much above 380cfm with max effort and .800 lift, at least for ones I have heard about and spoken to people on.
