Why does it kill you to ask such a question?????????

AI ported my heads. They only flow 283/214 @.600 at the moment. They will get worked on during fall/winter. Don't know yet if I should send them to AI again or try L. Elliott.

I would try LE, hand porting may be the way to go. Did AI CNC them?

Hi. I've tried to enlarged the plenum volume of the intake. But, I haven't some good outcome or improvement on it. What do you think will I need to do?
