I calculated about a half a point increase when swapping to TW heads and .039 Fel Pro Gaskets, but it sure seems like more, the TW chambers look a lot smaller than 6cc difference from the E7 heads... swapping gaskets aint gonna give you much though, definitely not worth the trouble.

Probably around a .2 increase
