Yeah. I went through hell and money there.......but i learned a LOT.

Really nice .300/.400 numbersAgree 100%. Here's what my Eddy's flow after HAND porting by a pro. Check out the mid lift numbers especially. These kill out of the box TF's.
.100 64
.200 155
.300 233
.400 280
.500 298
.600 307
.700 309
.800 311
What size intake valve ?Agree 100%. Here's what my Eddy's flow after HAND porting by a pro. Check out the mid lift numbers especially. These kill out of the box TF's.

I hate to "Be That Guy", but 250 cfm @ .400" would be a stellar flow rate--280? Never Sum-Ting Wong. I mean we are talking about SB Eddy's right? J.RobReally nice .300/.400 numbers![]()
Yea, those numbers look extremely optimisticI hate to "Be That Guy", but 250 cfm @ .400" would be a stellar flow rate--280? Never Sum-Ting Wong. I mean we are talking about SB Eddy's right? J.Rob
went back and looked around a bit. #1 on your red flags seems to be maybe not so red? The pic below is from a post made by Pittsburgh Racer. Speedmasters. Check out the flow at .100. Exhaust considerably more than intake.I don’t really get excited about numbers from anyone’s bench but mine….. because those are the only ones I feel can be directly compared to……. Numbers from my bench.
That being said, I see two red flags on the numbers on that hand written sheet from IM.
1-the flow at .100 lift is considerably more on the exhaust than the intake, despite the valve being 30% smaller.
2-84cfm@.100 lift from a 1.60” valve represents 15% more flow than what the area actually will flow.
When I see things like that it makes me question the whole test.
I’ve owned a flow bench and have been testing heads since 1992, and not once have I encountered an anomaly like that.
Can these be made offset like the Indy-Brock cylinderheads?The Bloomers are 200cc
They are absolutely a fair fight against anything that isn’t offset.
As people have said, all they are is a speedmaster head with a good port.
All standard port heads were developed for stock stroke stuff. So was the offset W2 and W5 stuff.
Well c'mon and share the et and mph difference. Ya can't leave us hanging lolHead porting, to me is like quantum mechanics or dark matter theory. I wouldn't even think of trying to understand it all. Maybe you're right, maybe not. But time and MPH do not lie.
I certainly have no reason to doubt the guy. Maybe he wrote the wrong numbers down?
After a full summer with those heads, I really don't care about the flow numbers. I just know they are a DRASTIC improvement over the TF's or the original hand port job. So I'm happy.........
for now.
No. and they don’t need to be. They already have been shown to support approaching 700 horsepower.Can these be made offset like the Indy-Brock cylinderheads?
I think his car is a stick and isn’t going to be optimal regards ETWell c'mon and share the et and mph difference. Ya can't leave us hanging lol
I wouldn't be to skeptical about PBR's flow sheet. He put a bunch of work and testing in his head work and his results at the track have proved it over the years.i'm very skeptical about the 2 flow sheets
I have never believed PBR’s flow #’s.I wouldn't be to skeptical about PBR's flow sheet. He put a bunch of work and testing in his head work and his results at the track have proved it over the years.

330 cfm out of an Eddie head seems “ robust” for sure.I have never believed PBR’s flow #’s.
Why?330 cfm out of an Eddie head seems “ robust” for sure.
Not a chance. Never in this born day is a Trick flow head going to flow 330.Why?
Larry Smith got 330@.600 out of Trick Flow 190
Yea and neither did Jim's 906. lolNever in this born day is a Trick flow head going to flow 330
