D2OE-AB Police Interceptor Ported Heads Flow Chart

I have both D2OE's and Edel 60669. My experience is with a 3800# street car that ran 11.50's with an HFT. 521 cubes

Really Richard not bad at all .Just a comparison my AFRs flowed 319@.400and 356@.600 hopefully you will have some compression and that will give you some bottom end .Good luck Doug

I’m assuming you just blended everything, those numbers aren’t great for a full port job.

I’ve gotten Eddy well over 360 and iron CJ’s over the same with minimal work.

Hears what the heads ended up flowing. As you can see a quality performance valve job is worth its weight in gold, I have not touched the intake ports except for the valve job. The valve job that was on these appeared to have only 2 angles and a sharp ridge, but the portwork itself looked rather nice. Lesson here is you get what you pay for in a valve job cost of the valve job $225

it should also be noted the intake valves on the befor did not have a backcut and the after numbers java a light backcut Nd that is also contributing to the excelent intake flows.

intake before valve job / after valve job.

.100 75 / 75
.200 143 / 169
.300 221 / 260
.400 293 / 319
.500 325 / 360
.600 349 / 384
.650 356 / 388
.700 358 / 391

exhaust before, after number are affected by a big ridge that need to be blended out, I'll post numbers after I get after them as the after numbers with the ridge where about the same as before. I expect improvements into the low 200's after I finish blending them.

.100 55
.200 119
.300 167
.400 186
.500 186
.600 188
.700 190

^ So Which Ones Do You Think, If Either, Ran Best/Better?

Was One(1) or Either Set Ported?

Neither set was ported. Street car performance was similar but you can get another 1/2 point of compression with aluminum. Those numbers on Dave's heads are stellar.

Stan Weiss's chart shows one set of ported D2OE's for comparison. If you've never been there take a look.

Blake ported a pair of D2OE heads which were very good.

Thanks for that link lots of Flow Numbers in it for all kinds of different Cylinder Heads!!I've seen it before on YB but it was nice looking at all those flow numbers again!!

For your heavy truck these will work just fine How big will the camshaft be? Doug

The comp 284x 4x4 cam I ran in my Ranger when I 1st built it did great I had dove c heads with factory 460 pistons. With a 3000 stall and c6 it did great ran 10.88 in the 1/4 at 3450.

Did you Deck the Block or Shave The Heads Much, What was Your Compression Ratio at?

I Take it, It was The Below Camshaft?

Same cam you have no deck work stock bottom end as come from Ford d9 block home ported dove  heads and Ford Motorsports g429 intake Holley 850dp compression around 10.1
