I'm rebuilding my 302 and want to use 1.7 rockers. It's bored over .30, e-303 cam, stock heads w/ 3 angle valve job. Which springs would ya'll recommend or can I keep my stock ones? Also w/ the lift 1.7's make, would my valves still have clearance w/ the pistons? ...what about my valve cover? I've looked thru previous posts, but I didn't find what I was looking for. I'll probably get taller valve covers just to be safe b/c there seems to be an on-going debate about that
