On the heads you may want to weld up the coolant passage , then just skim cut the head . We did not and it did not leak however it is not as supported as the HD cylinder.. If we do another I think I would feel better with the head welded at that point. I feel long term that maybe that bike we did may weep coolant.. at this point its been two years and nothing .. I may have gotten lucky

Just a item that I would look to do in the future

when i had talked to tman, i think this is something they normally do, but they had mentioned on the water cooled heads, that they weren't doing it because it is thin there.

they said they usually do a weld mod there but weren't going to be doing them on the water cooled any more

I would think he is talking about the welding in the port's not the coolant passage. Its a open hole on the head and seals against the gasket, the cylinder ( HD) has a support pad. that pad is not there on the S&S cylinder.

That much HP/TQ the Drive Train will not hold up well. Compensator Motor Sprocket, clutch, transmission and the rubber bushings in some rear wheels. If you do a substantial power increase then everything else will be needed updates too!

That's really not true unless you really plan to abuse the big motor. My bike held up fine for a lot longer than I thought it would.
