I'm not doing any port work so as to not shift the power band to the right. I am installing BC 272 cams and Supertech dual valve springs, ti retainers and alloy seats to keep from floating a valve. They will be doing a 3 angle valve job.

A couple options I'm considering. For the heat cycles the exhaust valves may endure I may just get the inconel standard size exhaust valves and keep the stock intake valves. I'm close to my build budget limit so if I can do both inconel exhaust valves and the black nitrided intake valves I will. But if I can only do one side would the stock intake valves be ok. Staying stock size to keep power band from shifting to far to the right.

I'll either be going with the AVO twinscroll garrett hyrbrid gt3076r cartridge or the ATP stock location gt35r so you'll know what the characteristics of the turbos will be.
