Hi, yes I was very conscious of not removing too much material, the lumps around the valves I didn't want to touch, it's obviously at the bottom of the plug recesses, and I don't know how thick the material is there.
As you say the heads flow good anyway, and this is a high port head so it's already worth another 10hp I read. Just a tidy up, I'm happy with that

I finally managed to bead blast the head, a lot of masking and plugging... I think the car it came from must have rolled into a field. It was quite mucky!
I then drilled out the two Advel rivets, and tapped the holes for ORS plugs, and gave it to my local to work machine shop for an ultrasonic bath.
It came out quite nice, like the block, all the nasty oil staining, which my parts washer wouldn't shift, gone.

Thanks for the heads up. I bought these through Modatek who support Cosworth historic engines ( apparently the Duratec is coming up to 20 years old, so they're starting to list the parts again) and have had quite a bit of correspondence with the fellow who did a lot of the development work on the Duratec with Cosworth. They are supposed to be a matched set, although I haven't weighed them yet.
He didn't mention anything about machining them. I'll mention it to him next time I write. IIRC these are 12:1.
Of course decking and clearance check is all part of good engine building practice
Correction. The pistons are 12:1.

I had a look today. I see no issue with the raised part of the piston.
Obviously I can't measure the deck heights, but by placing the piston on the head with a bit of plasticine, I can see there is no issue whatsoever.
From the correspondence I've been having, if there was, I'm sure it would have been mentioned.

It's amazing how long it keeps it's finish. I recon I'd probably need to do mine a couple of times a year if that. A wash and buff should keep it looking good.
I haven't done mine since it was initially polished. Granted it's sat in the garage, but it hasn't dulled at all.
I think the polishing burnishes and seals the surface. After all, Nuvite was used on American Airlines aircraft, they don't polish those very often. Although they are painted nowadays.

Well, I may be moving at the rate of tectonic plates, but believe it or not I'm moving... Still collecting parts for the engine, just clutch and flywheel to buy before all the rotating and reciprocal parts can be sent off for balancing.
Quite pleased with myself last week, as I was considering how I'm going to get water from the back of the head to the front of the car, since the engine was originally in a transverse configuration in a shopping car, and is now in line. I see people like Raceline, (whom I never was successful in making contact with, despite several Phone calls, e mails, and word of mouth...) Retro Ford, and others sell kit for just this job, but for several hundred pounds.
A bit of time Googling, searching forums, and looking at photo's on Google images revealed that the Ford Mustang 2.3 Eco boost engine looked promising, as a lot of the parts are interchangeable, and I believe it's the same block.
I found part numbers and part drawings, and decided to take a chance. I ordered the parts for $112.
They turned up Thursday, and YES! result Perfect factory look fit
