4 banger dual plug heads

anyone know or know where to find the flow numbers on stock dual plug 2.3 heads. After I get done with the body work and the interior i'm pulling the head to port it, also to do a few more mods while I port the heads. Thanks for any info.

.050"-30.0
.100"-58.0
.150"-86.7
.200"-110.7
.250"-130.3
.300"-143.3
.350"-153.1
.400"-158.9
.450"-164.1
.500"-166.8
.550"-166.8
.600"-170.2


Found this over at turboford.net. There are lots of great threads reguarding the DP head flow. The turbo D port head flows better...but 99% of them are cracked (including mine but it still runs fine). Porting should open the intake flow up to about 210 CFM and a good valvejob should get you 10-15 more CFM. The D port turbo head is good for ~250 CFM on the intake side with a max effort port and valve job. Not bad for a little 2.3 head....

I've got some stock and ported #'s...but they are at work. I'll post them tomorrow night. Did a bunch a few years ago for some dirt track teams.

hmm so some ported heads and a well planned out stroked 2.3 should be able to hit 200 hp mark.....haha modifications so far include short throw shifter from mgw, and a piece of pvc pipe with silicon charge air couplers from a isuzu diesel in place of the air muffler, and made a setup to bypass power steering.....coming soon elimination of the exhaust side plugs and coil, completly removing power steering.

Here's my ported #'s

lift Int. Ex.
.100 54 48
.200 115 90
.300 156 113
.400 179 129
.500 187 137

Just thought I'd revive this thread. apparently, the DP head is the hot ticket, according to this post:

TurboFord.net Forums: Dual Plug believers come inside....

I know where there are a few of these heads, one is cracked beyond using and might be a candidate for me to learn with.

is this going into a n/a 2.3 motor? then I would stick with the higher compression head vs the D port style head. which has IIRC 8.5/1. The N/A 2.3 non D port is 9/1. Not sure on the Dual plug head though.

boport in that thread from turboford did a great job with the dp head.
