Hi guys,

Based on the following rule of thumb:

"there are rules of thumb for figurin' out intake runner volume. Cubic inches times 0.50 for a good running street motor and cubic inches times 0.55 for a max effort motor."

What kind of cylinder heads would your recommend for a smaller displacement street SBC (i.e. 283, 302, 305, 307)?

Seems like most aftermarket heads would flow too much for these displacements.

Thoughts?
