Okay, thanks brads911sc, new exhaust valves it is, I've been toying with the idea of replacing the inlet valves for the larger 993 RS ones but need quotes for re-machining the heads for the larger seats before I take the plunge.
I had a measure of the crank at the weekend using digital vernier as I don't have a micrometer that size. I put the results against the dimensions in the book but the main bearings and the rod bearings while being consistant, don't measure up as per the 3.2 crank unless mine is undersize?
On a seperate note - Does anyone know what the part number is for ARP rod bolts to replace the standard items?
I've had a look and think it's 204-6005 but want to confirm before I order the wrong ones!
Also - What sort of difference is there between steel and titanium valve spring retainers? (apart from about $300!)
