Good 305 Cam, rocker, valve springs combo
Just like the title implies. I am looking into getting the Crane compucam 2030 cam, and 1.6 roller rockers, but what valve springs should i get? Do i need new pushrods? What are your opinions?

The 2030 cam has .423 and .446 lift with 1.52 rockers. With 1.6 RR's, you would be looking at about .476 lift on the exhaust side.
Crane recommends their 99848 springs. Here's a link to their specs, 99848 Crane valve springs. I assume your are dealing with stock heads with stock-width spring pockets.
I'm a Comp Cams man and would recommend you phone them for an answer. From the catalog, it looks like their 981 springs fit the bill.
