Oversize exhaust valves

I am presently in the process of upgrading the head of my 57 "A" to include stellited exhaust valves and bronze guides. The PO had the engine overhauled and it appears that oversize exhaust valves (1.375" vs. the original 1.281" dia.) were installed. Does anyone supply a 1.375" stellite valve? Scarborough Faire offers a non-stellite valve this size.

Thanks,
Ed

I think the late MGA came with a 1.34375" (1-11/32") exhaust valve. A stock 1622 seat and valve should suit your purpose and I'm pretty sure that was the stock exhaust valve for all MGBs. Should be easy to find. For oversized exhaust valves, go to 1.44" which was the Twin-Cam size.
