Question about to increase compression ratio and curious on whp and such

never had a chance to dyno it with my current setup but my pb times and trap speeds is in sig. runs low 12s and depending DA between 112-115mph on stock LQ4 9.4:1. im guesstimating around ~370whp? ~3700lb w/driver

planning on installing 243/799 home ported heads with 0.030" milled (from ~64cc to ~61cc) and planning on using MLS 0.040" HG.
calculators/calculations say SCR is ~11.7:1 (will check PTV with clay and such)

what kind of whp and times am i looking at with that compression ratio?

With that compression and head/cam combo I would think another 70-80 hp is within reason
