Valve reseating

[Ian Williams]

It is very hard to be sure from your pictures but something looks very odd about the exposed valve seat, almost as though someone has fitted inserts below the face of the block??? There would appear to be a definite step down to the valve seat, if it was not for that I would have suggested your plan for a new set of valves and a clean up of the seats would be all that is required, perhaps someone has put a 30 degree cut above the seat to reduce shrouding, in which case run with plan A!
