360 build. Is this good street build? Heads work?

I've run it .028 on the street no problems.
Someone i was talking to was actually running theirs tapping the heads by .0005 or so.... and it made more power that way rebounding off the chambers!
Cast or hyper cast would disintegrate in the scenario...but forged would take it...just change the rod bearing out every 2 races.lol

My thought is if OP's combo was too close at .027 there would have been some bad news from the dyno run he posted about. Could be wrong.
