A standard strap from the valve cover bolt to the chassis is fine. The amount of current that is being used by anything on your engine can and will pass through the strap and a 1/4" bolt. Granted a strap from the back of the block or head to the chassis is a little more clean (thats what I did).

Many OE cylinder heads have a restriction just prior to the valve seats. Careful enlargement of this area can wake up horsepower. Avoid grinding around good valve seats. These heads may not look pretty at the moment, but clean up, hot tanking, and new valve seats will follow our porting job.

For a pushrod engine with cast iron heads, out-of-flat should generally be .003 in. (0.076 mm) or less for a V6 head, .004 in. (0.102 mm) or less for a V8 or four cylinder head, and no more than .006 in. (0.152 mm) in a straight six cylinder head. Aluminum heads and performance applications should be even flatter – no more than .002 in. (.05 ...

The GEN III smallblock has already moved to an 8-mm (0.313-inch) valvestem, in comparison to the standard small-block 11/32-inch (0.343) valvestem. While this is only a 0.030-inch change, it does contribute to reducing valve weight, which reduces the necessity for higher-load valve springs and produces less abuse on the valve.

The best choices for big-inch stroker engines are W9, Indy, and Brodix heads. The valve spacing in the W9 cylinder heads allows the use of large valves. This head has 2.150" intake and 1.600" exhaust valve. The valves are spaced 0.066" farther apart than in most Mopar heads, and this allows more room for larger valves.
