Valve/valve seat questions, 308 heads

Hi!
"Rebuild season" is closing in here in sweden and it's time to get some work on my 360 Valiant. Found a pair of 308 heads for cheap in pretty bad order (donor engine had water in cylinders) so I'll have to do some valve work.

Found out that 2.02 valves aren't that expensive on summit so why not go for it? My concern is the valve seats. Haven't done anything like this before so I wouldn't know. But how much material can you mill of the seats? Is it possible for standard 308 heads(is it 1.88 intake valves?) to house a 2.02 with some additional milling? Valves and seats looks pretty rough so some work will be needed anyway.

The goal for the engine is an early power curve. Good bottom end power and rising to a peak diminishing between 4800-5500RPM.

Best regard
Carl


Leave the 1.88 valves in there and use the best valve job you can find. Unless you want to do more than just bowl porting its not worth the trouble of the bigger valve.
