I also thought the lack of intake bolts would be a problem. If the flange on the intake was thicker and the ports were o-ringed, I'd feel a lot more confident using it.
I have to get it out of the shop and back to the house pretty soon. I'll get some better pics.
Not much of a selling point here but I wouldn't feel right unless I spoke what I think is the truth. Regardless how much I paid for the thing and all the B.S. I went through to finally get one, I wouldn't use it for much more than a paper weight. That is in a diesel application anyway. ...and same goes for the Indy billet head I was hyping on back when.
If you understand expansion rates relative to heat, you will come the realization that the valve seats will not stay put on the big OD 12 valve configuration.
The only way I see anyone successfully running this head is to have the entire combustion chamber machined and replaced with some sort of iron alloy.
