I was told that with the 220/220 cam raising the comprestion ratio to 10 to 1 by milling .030 would help me see beter gains. I could still run on pump gas right? what pushrod should I use if I milled them .030?

well generally speaking, if you have a cam and are using 7.425 push rods, and then you mill the heads .25 then stock push rods could be used, if stock cam then minus the length that you mill the heads. hope this helps and if i'm wrong then someone will correct me I hope ahaaha.
