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

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.

So thats where we are as of today. i should also let you know that i have sold the GT3076r and am now looking at a GT3582R.

The plot thickens

Is it wrong that I think those valves look lovely

Great update Frayz. You may only post every 6 months or so, but at least they are worth the wait

Haha, yeah, updates should come sooner now chap. Im off work at the mo as you know due to a f'kd shoulder.
So as soon as im back at work i'll knock the motor together.
Typical, im off of work with all the time in the wiorld but cant do anything.

At least i have some fancy tools at work to make the job a little more accurate

Yeah, seems like my project has been ongoing since the year dot. However i am starting to see a light at the end of the painstaking tunnel now.

I know my build isnt as big and flash or big budget enabled like some. But im one guy, seemingly still a pup at 26 and builing my car at home.

Its no race or TA car... just enjoyable on the road and setup to take to the track
