Re: 4.1 crossflow, Iron head. Transmission options

There are several good online CFM calculators to determine how large of a carb you'll need to select. A 500 CFM carb is likely going to be too large even for the most radical 200 cubic inch engine. A 350 CFM may be closer to suiting your needs more closely.

Yes, bad idea as pmuller said. You never use the head gasket to open the chamber up to. Bolt the head to the block and flip it upside down and scribe on the heads deck surface using the bore as the boundary, not the gasket.

Also, V8 rods only have a chamfer on one side of the B/E for radius/filet clearance,so you will have to chamfer the other side before using them. If the are offset, you can also just trim the side of the S/E to keep it from rubbing inside the piston pin boss.
