Re: 393 clevor?
Your Building a detonation problem, the Open Chamber stuff is bad enough at 8.5-9.5:1 with a 3.85 Stroke and Domed pistons Your probably going to be in the 10.5ish Range. and with .060 in the hole and Crappy Combustion Chambers your looking for trouble.
Best to Spend the Extra $$ on the Correct Pistons and Keep the compression at no more than 9.5:1 with the open chambers and If you get a set of Ausie 2v heads you'd be able to push 11:1 providing you have proper quench (Tight Deck Clearance).
KB may have some Hypers that fit the bill and may only be around $150 more than the pistons your refering too. I'm assuming you looking to do this on the cheap?
Now I'm not saying what your talking about wont work or run, But its very far from being correct and Like I've said your asking for detonation issues, which will either destroy it, Make poorer power than it would doing it correctly or Require Race type fuel to operate OK.
And in all honestly, if you looking to build a decent motor the 2v Cleveland heads will get out performed by decent aftermarket wedge heads and parts are alot more common.
My advice is don't build a motor around 1 part your getting a deal on and everything else is going to cost a good $$ to get right.
