What is the head torque spec on the 800cc engine?

50 lbs.

just FYI,
The service manual says 40-43fp. Here's the page.

Thanks everyone. Where do I get a repiar manual for this rig? Has anyone tryed copper spray on the head gasket to ensure that it doesn't blow again?

You can download the engine service manual at the top of this forum section. It is a "sticky". As far as "copper spray", your best bet is to keep your engine temperatures down with some additional cooling. WC has got some cooling system upgrades. Give him a shout.

WC, no worries man. I'm sure the additional clamping is probably a good idea, especially when adding boost.

Ya sorry Mick that didnt come out rite, I ment I've done quite a few and had good luck at 50 pounds . Note to self "me": read your own statements before you post them!!
True we do add a little for boost I should have posted that also.
