Default Patriot Performance flow numbers

Just got my PP LS6 style stage 3 heads flowed! I got the heads Monday, I took them straight to Hi Flow heads to have them flowed. I took them there because someone just took a MAJOR head companys head there to be flowed. I'm not going to list the name to start a war. Anyways after some skepticism from Mike at Hi Flow, and showing me his heads. BTW his heads looked very nice. He also welds the chambers. PP numbers. .100=72 .200=151 .300=201 .400=250 .500=292 .600=321... Not bad for a "cheap" set of heads. Mike was very surprised and impressed. He said he couldn't believe that that head could be made for that money. He said it would cost him $1000.00 more to duplicate that head. BTW it out flowed his head by 51 CFM at .600!!!!!! It also out flowed the OTHER head. Needless to say I am happy that Larry at speed inc. sold and recommended that head to me. Just thought I would post, It seems like it's been a PP bash month. Thats why I WASTED my money to have the heads flowed. I had thought I made the wrong decision. Well now I don't. Good luck to all. Andy.

Great info. Was the test @ 28 on a 3.9 bore?

Any intake flow numbers with an LSX or LS6 intake in place?

I heard who's "OTHER" heads were flowed against the Patriots, and that really impressed the hell out of me. Some major $$$$ difference between the two heads. I think when I get the 383 built my stage II's may be for sale and I'll be upgrading to the stage III's.

Btw.. Terry, you going to start putting your "signature" on these?

if terry's #'s were all done with a pipe then the #'s are comparable to whats on their site if not i couldve sworn i saw other heads flowing like 250 with a pipe on teh exhaust...I'll do some research but im pretty sure.
