I got the data back from my machinist on what happened with my rebuild - they said that the head was already trimmed to the max and so they decked the block and head by 0.003" only .
It is a late 2F that has the combustion chambers that has the kidney shape like in the 3F.
The cylinders has also been over bored to 0.060"
According to them the compression ratio is now 9,5:1 . (I asked them to aim for 8,8:1 but it seems they had no option .)
Mark W states in various threads the CR of 9,5 in a 2F is acceptable. I will have to rum premium gas but the gas here is 95 so it may work OK.
The cam I am placing is the Delta Cam KC859-250s - so I need to find out what effect that will have on Dymanic compression .
The one problem is that the cylinder head bolts appear to be too long .
Could that be due to the fact that the head had been trimmed to the max ?
What do I do now - Just trim the bolt shorter ?
