Charles - I've no experience with supercharged engines , however I have always
converted both crankcase / block and block / head studs from BSF to equivalent UNF sizes.
5/16" BSF = 22 tpi , UNF = 24 tpi .
Seems to work on all my Ulster engines although my ex Reg Nice car has stated to leak oil
from the front of the block - I know this is BSF !
Just a thought .
