over $500 deep... not sure forever... but they better outlast my Dremels....

It will only get better looking........

Well... that took a week??? to get this thing cleaned, and pressure checked.... I'm guessing they were busy????


ANYWAY..... the head checks out, and it is flat! this means a cut of .002" or less will provide the mating surface for a good metal gasket seal.


This head will be getting half a valve job.... yep, half a valve job!



The intake seats, already with 3 angles, will get a very fine (400 grit) lap in, while the exhausts will get a full on 3 angle.


and I've begun the port work.... the intake side is all new, like OST-034 was. Buuut... unlike OST-034, there is a fair amount of port to bowl transition blending required. As to how much.... I'm following OST's first rule of porting... do no harm, so could I take more.... maybe.....




now as far as the exhaust goes....

but the exhaust I've got well in hand....

Here is a view down(up?) the bowls to the roof... notice the ledge(angry eyebrows)...???



Anger removed... and all without Botox....


and a view at the short radius, and the transition to the port from the bowls






more to come.....
