40 hp big bore deck height

[roadkingdoc]

is there an optimum deck height setting for my 40 hp big bore setup? thanks

As with any VW engine you need to look at all the pieces - what cc do the heads measure out to? (you never know if the heads have been flycut at some point)

Often times you do get a bump in CR from big bore kits - is running with midgrade or premium fuel something you want or do? or do you want to set it up for cheap bottom grade fuel?

thanks for the reply. midgrade is ok.

I would shoot for .040"(1mm)(piston to head clearance) and do whatever chamber work needed for the cr you need/want.

FYI - I set mine up for 8.1 with the square boss heads and AA big bore kit. As it turned out, I didnt need to use any shims. I run mid grade to play it safe and the car runs amazingly well.
