replacing the peanut cam eh?
Sounds like your getting the Summit/Crane Blazer cam. I ordered the Crane Powermax 2030 which has about the same specs. I had to return parts to my local speed shop and the 2030 + CRANE FPR was a even swap.
Need to get it installed. Should be worth 30-35 hp alone, + another 10-15 from porting the base/plenum.

I would go a little more aggressive, I am running a compcam.
.495/.503 218/224 and I wish I had gone bigger than that. The stock heads will hande up to around.470, I would look at something around there.
