Hello,
My 81 sc suffered from two broken exhaust side head studs on cylinder 1, and the leakage roughed up the mating surfaces between the cylinder and head. My plan is to machine a total of .25mm from the head and the cylinder to get fresh surfaces. (Not .25mm from each for a total of .5mm) Then I am going to add a .25mm cylinder base gasket on top of the 1mm base gasket already there to keep cylinder 1 at the same height. The cylinder bores are in great shape.
I would like to know:
1) How come there was not a 'ce-seal ring' in between my cylinders and heads as shown in the diagram from pelican below? (part # 6) I have seen heads with grooves in them to accept sealing rings or O-rings. My cylinders are Mahle 952N1 W15. I guess aluminum on aluminum makes a good enough seal?
2) Any tips and/or advice on mounting and machining the heads and cylinders would be appreciated. I'll be on a Haas vf6 or vf2.
Thanks,
- Andrew
