What size engine for the online/Youtube EC?

I don't fully understand the logic behind not permitting use of the RHS/EQ iron heads.

They are generally regarded as comparable to an edelbrock or speedmaster replacement head with regards to performance potential.

Sure, you can no longer purchase an RHS/EQ cylinder head new anymore, but plenty of guys already have them.

You also can't purchase J heads, or X heads or Magnum heads new either, but they are permitted

To me, the current rules essentially guarantee that the winning combination will have either an edelbrock or speedmaster cylinder head.

Perhaps nobody with EQ/RHS is interested in participating, but I think if there is it would be worthy of further consideration.
