Daveo/Joel   FYI on 062 casting heads. These heads are very prone to cracking in the exhaust area of cylinders 3/5  4/6..

Sorry for the additional memos/thoughts,however I feel this is very important on your build and that is if you use different heads or even use the 062 have your machinist open the exhaust ports too fit 1.6 or 1.65 diameter valves as it is important to rid the cylinders of exhaust and will also be advantages to use headers with 1 5/8" or 1 7/8" tubes to 2.5- 3" collectors for increase torque.It is a mistake of most guys who think having 2.02 intake valves are conducive to hi performance when faster exhaust system is more beneficial,unless you have dual quads or a 1100 CFM carb then you would need both..

Sal, all good info, especially for someone building a 383 for, say, a C3 Vette.    But in the case of my 'burb I think we're talking too much motor here.  I'm shooting for 9.5 ish CR - 10.77 is way too high for what I want to do.  The early 90's TBI system will be a limiting factor for me, even though I have upgraded the throttle body and will upgrade the fuel pump and chip, that system can only go so far.  

Daveo76   FYI the 383 stroker engine got it's start as a Blazer engine in Mud Racers in CA. then became an engine used in El Camino's, Cheveles,Camaros and then in Vettes,however gained their fame in Suburban's,Blazers and trucks with EFI,TPI induction systems.
