So wondering can a 54mm piston and cylinder work on a usually 52mm head setup? or do I have to buy the 30/23.5 head for the 54mm?

TB has a 54x63 jug, and I have them. Piston linked will only work with mild chamber mods and give HIGH compression, but I have the "right" one as well. My 95's with the big dome piston and modded head are a ripping combo:)

117 rips! $135 with gaskets, just a bit more than a 52mm setup. 54mm piston is a newer design, and lighter too. More in the AM, if needed. After 3, here...Just got up to let the dog out. Again:rolleyes:

will this set up run on 89 octane or e85? and this is with 23/20 head?

Either should be fine, if 91 isn't available at the pump. Watch the temps with the 89, and jet real fat for the e85. You may have trouble with fuel lines and petcock rubber, too, but the octane and oxygenation should make a good runner. 23/20 has about the same chamber as the TB head.
