Valve clearance on custom cams 964/993
Hi,
I have recently transplanted a '94 993 engine into my 964 (sacrilege some may say.....).
3.8l with 51.5mm intake and 43.5mm RSR spec heads built by Mamerow. The cam is a special Mamerow Engineering grind but no specific lift or duration details are available (I have mailed them). Rev limit on the remapped Motronic is currently 7200.
Just about to do a valve clearance check (engine is solid lifter converted) and I was wondering how common non standard gaps are for intake and exhaust or I will be safe going with 0.1mm for both?
Cheers,
Tom
