I have a set of eagles opened up for 2.14 and 1.60 apache valves. One side maybe exhaust needed seats. I know I hit 305@.4.
I needed to start removing metal in the chamber which was sorta defeating the purpose or using smaller chamber. I would like to do some more experimenting with them also just need time.
