I have a prepare Dove 427 SOHC set of heads with Comp Cams with specs that were lost.  I had a machinist more talented than I, and he generated the following;

1) I have 2 different top oiler marine blocks that are std bore, but will require an over bore. 
2) I have a 4 3/8" RPM crank and rods BBC journal
3) I have the tunnel wedge intake
4) I am looking at advice for piston manufacture recommendation, compression target range for performance/hot street,pump gas.  I have access to non-ethanol premium at the pump (commercial account). 
5) I don't have a car, tranny, rear-end, etc.  I think it is kind of moot since I have the head assembled and spec'd already.
6) Where do detonation issues start to show-up builds discussed/performed/bench built?
7) Ferrera Valves 11/32" hollow stem F2024 2.280  Intake, F2023 1.900.  Chamber not CC'd (I was leaning on Members knowledge).  Plan is to take them  and get CC'd in my Community College class (personal enrichment course)

Recommend Pistons compression, manufacturer, special considerations, etc?

Thanks,
Gary

Side note;
I have Coon Heads with a different set of Comps Cams specs (for blower build w/ Monroe Intake Manifold Australia, 8-71), Crower Billet 4.25 w/o rods or pistons.  I will be looking for same advice in preparing this short block.
