MG MGB GT V8 Factory Originals Technical - Buick 300 Alloy Heads

Just picked up a pair of these heads complete with valves, standard size as far as I can see.

Dan Jones if you are watching I would welcome any advice on how to prep these heads for a 4.3 or 4.6 engine for mainly road use and possibly an occasional track day.

Dont intend on using a wild cam with too much duration, but lift may be important with these heads
also believe these heads benefit from a larger exhaust valve and presumably will need harder valve seats for the exhaust anyway.

I posted a question under the Huffaker thread re optimising compression ratio because of the larger 54cc combustion chambers and to what pistons would be required in a 94mm bore to achieve a 9.5 - 10 to 1 ratio.
