Isn't it the cam that dictates the gap?

I run a supercharger and I don't care the TB is on the wrong side.

Cant see any reason why it would change over the standard rockers dude.

The clearance does alter with rockers purely because as the valve and pushrod grow with heat, the increased ratio of the rocker exaggerates this if you have say 1.5 rockers compared to 1.25-ish of the standard ones.

Nick you are still using 1.3's so you should be able to keep them more or less the same, the alloy rocker will expand a touch more with heat, so an extra 2 thou over what you usually use will not hurt.
