What roller rockers should i get? 1.52 or 1.6. Im kind of stuipd when it comes to some of the parts. Here is another stuipd question--Why roller? Also roller lifters or hydralic? The cam is going to be a mild cam, maybe the comp 2030. Cast or forged pistons? All this is going in my rebuild of a 2.8 into a 3.1. Thanks

well 1.6 would be better jsut make sure you dont have to much lift all together with a cam and them roller lifters and rockers is allot better then standerd just from so much less friction

 

The stock valve springs can only take about .440'' of lift.
