i got the 1.98:1 rockers off mace and they made a HUGE difference to useable power through the rev range and up top, if your going bolt on these are great

I'm curious;

With your different size options in spaces and throttle body's, which sizes give what advantages?

Ideal combo for an NA setup, if space permits, would be a 12mm plenum spacer and a 25mm manifold insulator. Generally the thicker the manifold and plenum spacer the more bottom end torque is made. In saying this though, going too large a plenum spacer is at the expense of throttle response. It's for this reason we recommend a 12mm plenum spacer for NA engine and a 25mm plenum spacer for boosted ones.

As for the larger throttle body, we really only have one type, which is a 69mm throttle body. We do have a LS1 throttle adaptor, but that would involve an all out custom tune.
