i have a set of se heads for my 103 build that yeild about 10.80 compression according to the harley chart.how can i get it down to about 10.01?

 

well, you can do a couple of things, first off are you running flat top pistons, or domed pistons?

you can swith either one out for a dished piston and recalculate. or as i recently did, have a domed piston milled down a few CCs to correct the compression.

If you have a lighter bike, like a Dyna and 93 oct. fuel or your at high alitude, over 3500 ft above sea level you could do a cam swap and or ignition work and you may get by with that kind of cylinder presure.

I have a 10.2 to 1 HQ build and im at sea level, but I also have a 10.8 setup for my bike (bigger domed pistons) if I ever move back to Utah, which is 4000 ft in my home town! using the same cams and ignition I have now will run just like it dose down here in LA.

you may want to consult and Indy, hand him your heads and get them CCed to see where they realy are and see what your options realy are.
