OST Cylinder Head Porting Services

A quality port job can add power,and ECONOMY, even while retaining stock parts! Because casting imperfections are removed, not only are power gains likely, but more even airflow promotes even combustion, which promotes cleaner emissions. More airflow, more power... less throttle angle required to hold a speed... likelihood of better mileage (if you can resist the urge :D )

BIG EDIT - Since I ALWAYS recommend a minimum level of work, I decided that pricing should reflect that minimum amount of service. I've condensed the bowls, and seats, tapering the guides, deshrouding and balancing the chambers, and the exhaust port re-taper into the minimum service I'll offer.

$600 (minimum service) to do the 16 bowls/seats, taper the valve guides, deshroud and balancing chamber volume, exhaust port re-taper, and polishing.
$150 to blend the intake guide bosses and to re-taper port roof - largeport
$175 to blend intake guide bosses, blend port walls, and re-taper port roof - smallport
$125 adding intake side oil drain
$100 for machining of the heads surface
$80 for cam journal deburring and polishing, and overall deburring
$80 for hand lapped valves
$60 for re-assembly
$60 to set valve clearances - your supplied camshaft

Loynings valve jobs - a few hundred to a few thousand

I can be contacted via email oldeskewltoy@yahoo.com , or bump my thread :thumbsup: NOW ACCEPTING PAYPAL!

from most areas in the USA... somewhere between $30 and $40. there is some cash to be saved by shipping USPS. Return freight is usually a bit more($10+) because I typically insure it for $800-$1000.

Hmmm, I think I heard you..., "What does an unported short radius look like??" Well I don't have a photo of those (ports above) prior to work, but here is another head showing the short radius before...

and after.......


Interested??? Send me an email - oldeskewltoy@yahoo.com

Bump...

checking/verifying chamber volume.....
Image


A bit of custom work to provide adequate clearance for those BIG cams....
Image

As well as doing the detail work that others don't......

Before (all except bottom left)
Image

After........
Image


It just doesn't get any simpler - view the exhaust port on the left as it goes from beastly to beauty........

bump...

VERY shortly I'll be offering flowbench services. I have not as of yet figured out how much I'll be charging. I also will not be offering this until I feel I can guarantee my #s.

To do this I've recently acquired some new equipment....

Image

and so I KNOW I'm accurate with setting valve lift...

Image




I've also had quite a few people help "train" me on my own equipment :lol:

the math involved in the flowbench makes my brain hurt :oops: ... so I've had a few people help dumb the theories down for me to simple actions(keystrokes) to operate "the tool" = flowbench



One service I'm planning to add to a minimum service.... is to show on a flowbench spread sheet, the progress of one cylinder from dirty/cruddy/old, to cleaned up original casting, to fully ported and ready to deliver. :D

I also plan on doing full port matching. This will be based on an hourly rate I'll set in the future.

Now TRUE port matching has nothing to do with hogging out the hole to fit the gasket...

What TRUE port matching is.... has EVERYTHING to do with making sure EACH PORT flows the same @ each lift point so that each cylinder get an IDENTICAL fuel/air charge so ALL cylinders are making the same power.


:D

Sorry for the hijack, But is there a post somewhere with before&after flow numbers, or a percentage if you don't want give up the numbers? d:)b
I haven't taken look at much of your stuff, kinda gave up after too many polished ex port pics.


Why yes... I DO have PROOF of what I can do......


Image

the little red arrows are pointing to 7.1mm lift, or cams from 1988+ 4AGE engines

the blue arrows are 7.5mm lift from the earlier pre 1988 4AGE engines

As the arrows show even with stock cams, my port work improves flow. Btw, those numbers were back in 2009, my exhaust port work has improved since then. :twisted:

Might be a long shot but wanted to see if you have a spare smallport head you could sell to me? I'd also need it ported too so all those charges for services would be added on of course. Thanks!

Hi this is slightly unrelated but I figured since 4age head work is what you do, you might know these numbers off the top of your head



hello all, I'm in the middle of rebuilding a Small port, it's a mild build, balanced bottom end, .020 over, etc........ I am sooooo close to having it back in my hands but my machinist just needs a couple specs before I can get it. so i was wondering if anyone would know off hand some numbers...
WHAT IS THE OE HEAD GASKET THICKNESS COMPRESSED?
OE PISTON TO DECK CLEARANCE?
OE VALVE TO PISTON CLEARANCE?
thank you for your help

1.2mm is the OEM gasket compressed thickness.

OE Piston to deck is unreliable... I've measured USED engines I've ASSUMED are original @ .002" to .003"

The OE valve to piston is somewhere in excess of 7.5mm because the engine is none interference and so with stock cams(7.5mm lift), the pistons do not hit if you break a belt.

New service - adding an intake side oil drain - $125.00



Image


Advantages: 1) minimizes some oil blowby (that happening on long left hand sweepers), 2) helps oil drainage from the head
