Xe268h fully ported heads 191/199/202 hp @ 3000 rpm.

All 3 with way more cam than stock made 27-38 hp more than stock 318 at 3000 rpm and even though none showed cammed engines at 2000 and 2500 rpm I have no problem seeing at least tying or even a slight or decent raise in power above the stock low cr 2bbl 318 at 137 hp @ 2500 rpm and 112 hp @ 2000 rpm with headers.
