Thanks for the info folks -

I know about esslinger and RacerWalsh, I bought the springs, valves, etc. from them. I will check out Extrudehone.com for more info.

A friend and I are building a custom header with 5/8" tubes to take advantage of the new volume.

Was over zealous and got head work done before I P-n-P'd head; didn't feel comfortable doing that after getting the new seats, and new valves in there.

<b>Will this be a critical error in performance? If so, what can be done now reduce the "performance damage"? Does anyone know if another TB will fit on the 2300 manifold that is larger in diameter?</b>

Also, made a 3" piece of exhaust pipe to replace the "baffle/silencer" in front of the TB. <b>What's a good insulator?</b>
