yes, you'll gain compression and some lift with the 1.6 rockers. Flow vs stock X 2.02 I believe would still favor the Mag head. EQ mag heads would even gain more flow, and can be bought for 590 for a set through jegs bare casting. They take stock mag head valve train. 590 plus 200 hughes spring kit and valves/rockers would be free, literally. EQ's come in either bolt pattern
