Class!

 

Not content with having exhausted every excuse in the book not to get my car done. Ive now dislocated my shoulder, so the fun and games are paused yet again.

Im gonna need better excuses soon. Lol

 

How did you do that?

 

Kiting last week mate. Aerial transition to landing reversed 2 wheels. Looped the kite on the landing and got ripped over. Landed on my left shoulder and then got dragged for about 30ft. Wasnt that impressive to be honest and a looked a royal **** infront of a load of people.

That will teach me to show off

 

Ouch!

 

Ouch

 

Lol, look what arrived this morning. How frustrating now i cant do anything with them. Grrrr

Still, they look pretty, Supertech Racing one piece valves.

Stainless intakes with nitride coating and Inconel exhausts.

 

Have you read this thread yet Frayz.

Cheers Neil, yeah its a promising read.

Stuck at home at the mo with nothing to do, so decided to clean up all the imperfections in my head ports. Intakes have been left rough'ish, while the exhausts are almost polished.
The heads are having the valve seats pressure checked at the mo. Then they can be washed and reassembled when they come back.

 

Valves/seats have now been leak tested and are ready to assemble. As soon as im fixed up and back at work, these will be washed, re-inspected and assembled.

really pleased with the way the heads are shaping up now. Lets hope they do the business once shes all built

 

So then, what else you gonna do when youre stuck home with a f'ked shoulder and cracked ribs?

Port + polish your heads

Bored today so armed with porting tool, carbide burrs, sanding drums, brass wheels, mops and soap i set about cleaning up my ports.

Actual port shape has been largely uninterfered with but all 99% of all casting imperfections and flashing have been smoothed. Also smoothed in the roof angles towards the valves slightly and cleaned up the dogleg area in the exhaust ports.

The intakes have been finished in 80 grit by hand and have a nice smooth key. The exhausts have been polished to almost mirror. Really hard to photograph, especially with a phone, but here you go.

Just a light lap left to do of the valves before a final cc check, wash and assembly.

Intakes






Exhausts

 

You could have that propped in the front room while you've got Jeremy Kyle on

 

very nice Frayz

 

Lol, nah all done in la'garage

Did very little in the way of opening stuff up as i really dont think the heads need it. Just cleaned up obvious crap casting areas and made sure everythings smooth. I didnt blade the dividers either. Just sharpened and finished with a clean little radius.

 

Spot on Frayz

 

What is the dog leg they talk about?

Looks lovely Frayz

 

Pete,

The dog leg is the port from the front exhaust valve. Its most clearly seen in this pic here.
The port on the right you can see that the exhaust gas has a nice clean uninterrupted journey from the valve heads to the exhust port.
The port on the left however has one run thats slightly twisted from the valve head to the exhaust port. And the worst offender is the front most valve. This has quite a wiggle to get from the valve head to the exhaust port.

Subaru exhaust ports are not symetrical like the intakes are.

Hence being termed the dogleg.

 

Valves all given a light lap today. Very light with only fine grit paste just to ensure the seats were 100%.
Took it slow as my shoulder was killing, but i had sod all else to do. lol

Just wash, assemble and final cc to go

Really hope these heads work as ive spent quite a bit of time on them now.

 

Should stuck the lapper in a drill

 

Matt is that your Spurs i can hear clinking together?

 

Have you seen my stetson?

Unfortunately I have seen it done

 

So have I. Gotta love a cowboy build.

 

lapping tool brings back memories of me being a clueless 18 year old with the head off my OHV from my mkI xr2...not much has changed

 

Perfect tool for the job, why change it?
Except the sticks are now plastic instead of wood
