Ah well back to the drawing board had all the bits done and ready



Good to go set em up and everything looks good



Welded them in and everything looked good till I got them home, Checked them and its distorted the entire Head by 17 thou end to end.
So back to square one again.

or actually further back than I was when I started,*%$.

I am going to get a couple of blocks of wood and try and get the distortion out on a fly press today,Its a bit of a cowboy way to do things but the head is scrap at the moment so the way I figure I aint got anything to lose!

The fly press method worked a treat after forty or so minuits of squashing and turning and bending etc it is within 2thou end to end so well within tolerance.



Happy again so I assembled the bodies





and dropped them of along with the head for a skim, re face on the injector plate,gas flow yada yada yada!

We used to do a weld repair on Ford cylinder heads. I believe they were Escort and they used to crack between the valves. We did enough of them that we built a steel fixture to hold them while welding and then used a good solid preheat. That would keep them within tolerances so that they could be easily machined.

I guess the important thing to check is if the cam tunnels are still true and the cams turn freely

Oz, it might be a good idea to put that head in the kitchen oven and heat cycle it a few times to season it before assembly, and to recheck it again.

yea Grumm
that was my main worry the cylinder side can be skimmed, that was the plan anyway but the cams like to be straight!
I put them in after we flattened it and they appear to be good.
I will re assemble when it comes back from the flowers hmmm i aint sure thats the right spelling and re check, they may need a bit of scraping out but as I say they look ok

you might have a point there Wobbly it would stress relieve it I suppose, the thing to do would be as peter says and bolt it to a plate and then heat it on a high heat along with the sunday roast yummy roast pork spuds fuel injected head yorkshire pudding and by the time I have finished dinner it should be cool enough to assemble, but seriously I think you are right.

Good work Oz, and the idea of heat treating them (we used to call it "Normalising") is great. I've seen many an engine or cylinder head roasting away in an oven, but with the Sunday roast? Do you remember what you used to buy from the butchers when you were drunk, and when we shared a house & kitchen? My missus nearly fainted one Sunday when she opened the door and there was half a pig's head bubbling away.

LOL Happy days, Get em while they are hot mmmmm!! lovely bit of a bummer when the brain drops on the floor though. I still think the foot pump and the beer was the best one though, A barrel of beer  and  no co2 a bit of creative pipe work and oila!! beer on tap it goes well with a nice roast head.

Well after 3 months of phone calls and expectations I have a date for the completed head work.... end of January almost 4 and a 1/2 months after it was dropped off, the original time that was quoted was 3 weeks!
It seems that everything on this project has huge time delays,it was the nitrous on the original build,from injectors to the controller,then the gauge blowing itself up on the first run on the salt.
Ho hum never mind if it was easy and straight forward everyone would do it eh! hopefully the results will be worth it.

Have a merry Christmas everyone especially the ones that aint havin such a good time of things at the moment special wishes to Willie and Sheri

All the best Oz
