The same applies to a gasser...there is no good way to thermally isolate the 617 intake due to how its mounted....but internal ceramic coating will reduce heat transfer to the intake charge.

If the head stays below 250°F. and the intake charge is 250°F. (est.), how will the internal ceramic coating reduce heat transfer to the charge?
The head must be considerably higher than 250°F. at the intake ports, due to the proximity of the exhaust for this coating to be effective?
