Morning, I have my 500 AVL top end off at present (long story) and found this, should the valve seats stick out so far?
Just doesn't look right and I have never seen seats that protrude so far into the combustion chamber before, not sure if bad manufacture (3000 miles) or of they have dropped (but both the same) or even if that is what an AVL head is supposed to look like, what do you think guys?
