Ken: Looking Good! Those should do the trick. Are you still planning on future blower install on your 292? If so you might want to possibly consider having a thermal ceramic coating applied to piston tops. Hyper pistons tend to "reflect" heat and will give you hot spots. You may experience detonation problems. Detonation will more likely be experienced at the lower RPM's as the valve overlap and retarded ignition will yield there greatest net "effect" on the combustion chamber and flame front. As RPM's rise and exhaust pressures will stablize and more evenly balance the intake. The blower causes a "gulping or pumping" effect against the (lower atmospheric) exhaust side of the combustion chamber at lower speeds. Anyway you get the picture. You may want to also consider smoothing out the chambers to remove all sharp and rough edges, as they will also aggrivate detonation problems. You can also have the chambers ceramic coated. Update, and let us know your future build plans?
Think Chevy!
