So I got offered another very high end set of E heads by a member. Now getting those, could not pass them up. Would cost me far more to get them made and have the capability to make more power than I need. Gabbys max E heads. 404cfm. Mikes were 414 I was told. And I know, (John) cfm is less than half the equation. But its a number us non head porters can kind of use as a ruler.
Called Gabby, nice guy and willing to talk. He has done sets of these heads by the E head big dogs, Kinsler, Lil Jack, Dwight. Mentioned more but cant remember them all. Gave me dyno HP numbers and said peak HP was at 7500 with 535s. And if I wanted to run a 505 it would be 7700-7800. Pretty sure this was with his heavily ported Victors. But the BOPs seem to peak in the same range.
Except for Marcellas BOP. 8800-9000.... thats over one thousand RPMs of "pull" difference. Out of a 565 no less. Living up to your knick name Magic Man.
10sec, you might want to invest in some Depends for you first full pass. Mikes E heads are the baddest ever. You will now have the baddest High Ports ever to go along with the best BOP ever. He told me he though John could get 450, maybe 460 cfm out of the HPs. And you know they will run better than the flow numbers.

Thanks for the nice words.

And the HP model head did land just shy of 460, was a bit surprised it was that good. Kinda didnt think it would get there.

Best of luck on your build !
