In ported form, to see the diff. between those and the #'s you just put up earlier with the 22* back cut. I'm assuming these were ported #'s you put up. Said another way, A comparison between a full on set with stock Eddy valves and a full on set with the 22* cut.



First off: Best bang for the buck SB head out there today: 2.02" Magnum R/T bar NONE. That being said, it is iron, and there are guys out there who think if it's not Aluminum, that it is junk. But I'm not one of them so, there is my opinion.

Ok....... you wanted to see flow #'s from E heads... Well prepare yourselves. Here we go:

I'm just going to post intake #'s just to keep my sanity (somewhat)

First up, E heads I did earlier this year for Coke Bottle Kid:

LIFT---AS CAST----STAGE1-----STAGE2
.100"--63.8-------63.8-------65.6
.200"--124.2------127.7------135.2
.300"--178.7------185.3------197.7
.400"--208.4------217.4------233.2
.450"--218.0------232.9------245.0
.500"--227.0------241.5------255.3
.550"--231.8------245.0------265.7
.600"--235.3------252.5------274.6
.650"--238.1------258.8------279.1
.700"--239.8------265.7------283.9

All those tests doen with stock E brock valve, no BC's
The Stage 2 job was'nt MAX effort, but it was close.

Here's a set I did from TN:

LIFT---ASCAST---STAGE2
.100"--62.1-----61.6
.200"--123.5----135.5
.300"--177.7----195.4
.400"--208.7----234.0
.450"--225.1----246.6
.500"--241.5----256.3
.550"--244.9----264.7
.600"--248.4----258.7
.650"--248.4----258.7

I did'nt push the short turn hard enough on this set. Again straight 45* no BC.

Here's a set that I did not port, these were done by a shop in GA. And Dwayne did the VJ and 30* back cut the valves. This is the set that is for sale on ebay right now. Owner is getting rid of them to get some INDY 360-1's for a 416, and I listed them for him after flowing them. I would consider these Stage 2 port work. The porter pushed the pushrod pinches hard enough to break through on 2 of them, and Dwayne sleeved them.

LIFT--EBROCKFORSALE
.100"--70.7
.200"--131.8
.300"--189.8
.400"--233.9
.450"--252.2
.500"--269.1
.550"--272.9
.600"--260.2

And finally here is the Ebrocks I just finished, with an out of the box port, but a 22* BC valve. I was a dumbass and was'nt thinking, and BC the valves before flowing the head as cast, so I don't have #'s on these heads with the stock valves right out of the box The #'s are so much better than the other as cast heads that I have flowed, that I would assume alot has to do with the 22* cut. Also I have to say that these had a very nice VJ on them, as they were used off of a Dirt track car, and this was not the Ebrock VJ that I am used to seeing. So #'s are kind of distorted....

LIFT-----AS CAST W/22*
.100"--74.2
.200"--138.7
.300"--193.2
.400"--232.8
.450"--242.5
.500"--247.7
.550"--253.6 (Bad turbulence)
.600"--250.5
.650"--246.3
.700"--246.3

Also note, all the other out of the box E heads kept pulling to .700", but the BC prevents that on this set. You do sacrifice high lift with this back cut, no doubt about that.
