I will tell you this. The Tman 577 is a very quiet running cam every time, no special anything needed to make that happen.
Here is a dyno sheet, stock block 103
Specifications:
103'', PORTED HEADS 80.2CC, TMAN 577 CAMS, .030''HG, STG. 1 ROUND A/C, FULLSAC HEADPIPE, RECORED CVO MUFFLERS, REKLUSE TQ CLUTCH. STOCK TB AND INJECTORS

with head work.
Those are good numbers but with head work, so what was the static compression on that? Do you have any charts with an 80"er n the 577?

577's in 103ci
I have t-man 577's in my 2013 Fatbob. I have upped the compression 10.5:1 with SE domed forged Pistons. No headwork. 102.33 hp, 109.85 tq. Comes on strong around 2500 rams. Great Cam. Dyna attached.
Next is the headwork......suggestions anyone? T-Man has suggested the T-man Street Performer 103 for about 115/115, that is with a throttle body.

How much were they decked to achieve that compression. I'm looking into building something close to this! Who did these heads, I need to get mine done this winter.

They were decked about .040, all new parts but original springs were tested and pressures equalized. 1.9 intake valve, 1.575 exhaust valve. AV&V valves and guides.

It wasn't to small to make 114 or so square with a solid torque curve. Stock throttle body and injectors, stock 103 block. This is not a high flyer, these results happen consistently.
