This pertains to IHRA Stock calss. Can I run the '67 915 heads on my '64 426 street wedge (365hp) or am I restricted to the original 516 head?

Looking at the figures it seems the car will fall into G/SA but not sure. The car is a '64 Plymouth Savoy 2dr sedan and I believe the engine has been factored down.

Any help would be appreciated.

Jim
