Pulled the head apart today to clean out the galleries and de-coke the valves and chambers.
This head was rebuilt, ported and installed on a 2.0 that only ran for 60km before spinning a main bearing.
There's some scoring of the cam bearing journals . I polished them up and I think they'll be OK. I'll keep an eye on the oil pressure.
Springs seem heavier than stock and there's titanium retainers in there. 8mm stems too.
Inlet porting is pretty extensive, guide bosses have been completely removed in both inlets and exhausts.
One bearing cap had a hairline crack and snapped completely when I test fitted the cam. I've put another in there from a 2.0 head. (Not really ideal, I don't recommend it for you kiddies at home.)
Next time the head comes off I'll get the cam tunnel bored.

Gasket is a Group A motor sport gasket 1.4mm uncompressed compared to 1.6mm of the metal gasket I pulled out.
I replaced the outer CV boot and repacked the CVs today.
There was some other engine stuff to sort out as well.
When starting the car it will sometimes backfire which is not a problem in itself but the cabin fill with the uncombusted petrol. So I went looking for firewall holes.
There's gaps around the clutch cable dodgy repair, seam sealer fixed that.
There was also a gaping hole in the steering boot.
I replaced it and fabricated a new stainless steel heat shied.

I had to do some work on the carbs too.
The ram tubes were painted black when I got them and I never gave it a second thought. Turns out that the paint isn't petrol proof and has been coming off. I guess the motor's just ingested it.
I've cleaned the paint of a couple of them and they polish up OK so I'll leave them polished.
I've also increased the chokes from 32mm to 34mm to aid with the airflow. Torque was never an issue and I'd prefer a few more revs over low down torque I can't use.

Looks good Pete. BIG valves! Haha. Nice!
It lives, and it's louder and faster than ever before!
More to come.........
Pete
By the way, Pete, did you Mic that tunnel on the cap you replaced to check for ovality? I would assume that it should be pretty close, within a couple of tenths, but i'd be wary of that... :)
Did the best I could with the tools on hand :)Quote:

Reminds me, I must go and get some plastigauge.
As I said, it's not ideal, should see me through the next season or until I get the other car on the track.
Pete
Motor went in today. Here's some pictures.
