Valve Guide / Cylinder Head Problem

Valve Guide Issue

Need Welder or replace part.

I pressed new valve guides in my had. Bore was 13.021 & guide diameter 13.083.

For some reason I got a crack of the intake valve. It cracked during the press in process. It did not crack all the way through, only in the section where the thin are of the inner part of the valve guide.
The crack is visible but on the side close to the intake wall.
Might happen due to aging affect. Porsche allow a pressing force of 0.mm. I was 0.002 out of spec. 30 year old material. Dammed

Who has an Cylinder head 2.7 MFI left and what to sell it for a fair trade ?
Or who can weld my cylinder head ?

Greeting Bob

are you saying the aluminum cracked dwn in the bottom ??

well, bummer. now you know that that was too much interference. i have a ton of 2.7 heads, but no MFI ones.
