Hey guys!

We are now ready to post the results of the machine work from post 01 3L oval port heads machined to work with split port intake manifolds. This is a BOLT up service, once you get your heads back everything will bolt up just like your stock split port hardware. For those unaware the benefits of using the 3L oval port head machined to work with split port hardware are the following:

--No plugging of your oil drains on your 3L block!
--More efficient tumble port design
--Heads already come with 3L valves saving you over $250 from having to buy new
--Up to 15% more flow then our PnP split port heads
--MASSIVE flow upgrades from stock oval port
--No seat work saving money and increasing reliability
--CHEAPER THEN OUR PREVIOUS SERVICE!

For the flow minded here are the numbers at different rates of lift in thousandths of a inch:

Intake
100 - 121 CFM
200 - 201 CFM
300 - 252 CFM
350 - 280 CFM
400 - 292 CFM

Previous PnP split port heads:

Intake
100 - 115 CFM
200 - 180 CFM
300 - 230 CFM
350 - 256 CFM
400 - 260 CFM

Oval port Exhaust
100 - 80 CFM
200 - 131 CFM
300 - 182 CFM
350 - 212 CFM
400 - 218 CFM

PnP split port Exhaust
100 - 74 CFM
200 - 118 CFM
300 - 171 CFM
350 - 199 CFM
400 - 202 CFM

As you can see these flow up to 15% more then our previous offering

The PnP service includes:

-- Complete disassembly of old valves/springs
-- Dunk tank bath in cleaning solution for a BRAND NEW appearance
-- Deck resurfaced if needed
-- Welding of center injector valleys
-- New injector valley cut in to match split port
-- Porting of intake and exhaust ports by hand
-- Porting of combustion chamber by hand
-- Dimples added for LIM gasket to drop into place like factory
-- Complete assembly of valves, springs, and retainers
-- 4 angle valve job on intake and 3 angle valve job on exhaust
-- Replacement of any guides not in excellent condition
-- Flow matching between all intake and exhaust ports to assure equal flow through each valve
-- Wrapped in shrink wrap to prevent foreign matter from entering cylinder heads

Retail price is going to be $1195 plus any parts that may need replacement (valves, guides, etc), and shipping. There is one picture below to show work in progress and I'll have finished pictures next week. They look factory and you would never know they underwent massive surgery!

I'll be out of commission till next Tuesday so there may be a delay in responses but I wanted to post this because I know so many people were waiting on the results. I'll try to get back to all questions by Tuesday at the latest. Thanks everyone!

Jesse....results look good. One question though. On the oval ports there's a 13cfm difference on the exhaust at 300lift. Can you explain why that's the only point where there is a cfm loss ont he oval ports? Also any predictions on how this will affect the gains?

On a side note...you have been PayPal'ed.

can u fit svt cams on those heads or are the 3L cams better to use, either or i am buying these when i get back from iraq

That is a typo, thanks for spotting, I have now edited the first post to reflect the right number.

For reference, what do the stock heads flow?

Jesse,

Forgot to ask this in the email, but with the chamber work what should be my final compression ratio with these?

Final will be right at 9.9:1 CR

How did you figure that?

I sure looks like you took out more chamber "meat" then I did.

I did more work to the area around the valves to give it better unshrouding. However you really dug into the heart shape and the middle lines of the ceiling.


I figured 10.07 CR for untouched oval port heads.

I figured mine in the 9.85 CR range. Mainly from removing the small ceiling hump and valve deshrouding.

Going from my measurements I would think with the material you removed it would be more like 9.7 CR.

What did you come up with for original CR?

any comments on the fact that the injector is still off to one side and not in the middle... i know the split port manifold dictates the location of the injector, but how would this affect performance vs having it in the middle.....

wow. gotta add this to my list of must-haves for the 3L upgrade.
