Rebuilding Big Valve 8v Head

[MerlinGTI 3]

Ive bought a Longmans big valve head (8v) second hand, which although visually looks in fantastic condition I would like to rebuild for peace of mind. Obviously its going for a skim/pressure test and im going to have the gasket surphaces re faced anyways.

 

My main question is will I encounter any problems getting the seats 3 angled? I ask as it has modified valves etc.. My machinest is fantastic, but hes no Richard Longman! I know I will need to re-shim the bad boy, but other than that?

 

Also will the valve stem oil seals be of standard 8v guise? or are they likely to be different? Pug still sell shims?

 

Cheers
