Boost on high compression engine

Boost on high compression engine
I've modeled an engine out with a calculator, it should cover a lot of what I need. I am using an h22 block, h23/f22 crank, h22 head, f23 rods, k20 (slightly lower compression) pistons or custom pistons (I used 4.7mm dome and 30mm comp) for 87mm bore, head gasket will be close to stock size (multi layer metal). I came out with 10.58:1 static compression, 2.3l, Rod stroke ratio 1.48:1, and .39in piston to deck height. I don't know what cam or valve setup I can used, probably just beefed up stock.
That's the engine, I want to run methanol and a centrifugal supercharger (14.7 max boost, that's unrealistic), I want to run the charger as cold as possible, so I'd use a air to water intercooler and methanol injection. Other things, no egr, slightly rich afr, no tb coolant, tb before charger.
Help me out I'm just writing things down. This engine could run at good power without a charger, I think I could realistically run 4psi boost easy. Also do you think my piston deck height is good enough?

DO IT ON ALL FOURS
Re: Boost on high compression engine
What the hell is your question exactly? Is the deck height good enough for what? There have been multiple builds at 13.5:1 compression and up to 30 psi of boost with E85 as the fuel. Where are you going with all this?

Eh, just a question to see what people had to say about it. I know it's confusing, I ramble. I want the highest piston dome I can have, also I just want to know what kind of valve train I can fit here. I haven't really messed with the top end of an interference engine, assuming this would end up being an interference engine. I have a hard time picturing that part. Basically I was all this or better without smacking a valve, that's a non forced induction question I guess.
