Default Question about Supertech ring gaps and PW clearance

I am rebuilding my 99 1.8. Planning on pump gas 93 octane, 300-350 HP.
The Supertech default specs for pistons are below

Bore: 83.50mm
Over Size: +0.5mm
Comp Ratio: 8.6:1
Volume CCs: -4
Head CCs: 50
Comp Height: 1.201"(30.5mm)
Stroke: 3.346"
Rod Length: 5.228"
Pin Diam: 20mm(.787")
Weight: 293grs

RINGS
Top : 1.00 mm
2nd : 1.20 mm
Oil : 2.75 mm

PW clearance: 0.07 mm.

Can others running Supertech chime in these values are ok if there are better values that have been "battle tested".

Thanks
