Hi Bob,
I too would suggest you stick with what you've got. At 30hp and decent compressions you're right on the money. Any of the new cylinder heads, good and well made that they are, wouldn't give you much more, you probably wouldn't feel the difference on a section. If you're trialling through the VSCC you couldn't use any of the sixties heads as well as they wouldn't be eligible. If you're after a little more bottom end and mid range power/torque you could try getting the compression up a little by skimming the head to the limit of the valve lift and ensuring the pistons are topping to the deck of the block. Other than that; if the head is installed and you're not having gasket or plug problems; in my humble opinion you're best sticking with what you've got.
Photos of heads old and new are shown the Speedex site.
