well its blowing again on number 6 again, ive got no margin for error so ive decided i want it machineing.
ive made a flat base and got it spirit level square it bolts to it with the t4 turbo flange.
if it needs anything to clamp to it can just be welded to my base plate now.




im hopeing now ive done that any machine shop should be able to skim it easy like a cylinder head.
