Wiseco Hd2 Ring Gap

Been building my engine on my own and taking everything slowly. This is my first high horse engine I've built myself, seen a ton of debate over ring gap.

I personally called wiseco and was asked how much boost I plan to run (30-35psi) and if It would be a street car or dedicated drag (street) around 600 wheel on kill with 10.5:1 comp.

I was advised to use .005" per inch of cly bore (82.25) for the first ring and .006" for the second. Which would set me up around .0017 first ring and .0020 second ring.

Everything I've seen online is even more loose than that, any suggestions?

I used .020 top .024 bottom on my last motor, made over 700 with no issues. I just put together my new motor with the same end gap.
