Don't wimp out lol, or stay conservative, if you want power out of that 360, then build power, i've run the KB107s with a small comp cam, it ran well, but "nothing" like the 370 i did up with KB190s, XE284H & RPM intake with a 750dp, you will be much happier trust me, you'll get the quench you need, & it'll run on pump premium, the comp. will be around 10.3/10.4 if the heads haven't been milled, i ran completely stock 915s, 2800 stall & 4.56 gears, it had BB power, this was also running PS & PBs, The KB 190s are safe to .600 lift if memory serves me (this is with un-milled Js), with your 915s haveing 202s, you might want to consider the XE285HL, if you can go .040" or even .060" over, you might want to consider that, mine never ran hot, never any detination, you can run a step or 2 colder plug, my cranking pressure was right around 190 psi.
