Google will quickly give you the specs you want. Heads used on these motors were S&S Super Stock for 4" bore.

Not quite sure about "max it out", but.............
Most all parts are available from S&S
If you have a bare crankcase, I would recommend a S&S flywheel set, your choice of pistons to match cam, heads, compression, etc. I'm using a reed breather in mine with a little bump in compression and a little better cam as it's a long distance touring bike.
Decide how you plan to ride this bike, maybe talk to one of the shops with your plan and see what they recommend.
Good luck with your project. :missed:
Need to be careful :dgust: , those 4" cases can pull cylinder studs out. Pay attention to cylinder head torque specs, and hope for the best. You may want to consider stud saver kits. :up:
