Right, redoing the top end and have been let down by a certain Manchester dealer that's sent the wrong gaskets twice and now ignores my emails so that's a dealer crossed off my list! :evil:

Anyway, mugello 186 with dowel head, so a mark 2 if memory serves.

I've put it together and checking the squish with the 2 v method as in stickys manual Im getting a squish of 0.9mm using a 0.3mm head gasket (which actually measures at 0.2mm on my verniers) so if I use a 0.5mm headgasket I should have a squish of 1.2mm (assuming the gasket does measure up at 0.5 and not less?

Sorry for what seems a daft question but just need to run it by some of ye that are building engines much more than I do

Yes Paul that would appear correct and would be spot on, but if in any doubt measure twice (or more) ;)

that's the one Lee and considering he's one of only 2 official importers for the muggy / imola / monza etc I was a bit surprised at the crap service.
