Default Do dual valvesprings hurt cam lobes?

Seen something about this with the patriot golds, can't seem to find it though.
Would the PSI maxlife beehives be a better choice? Running a 383 w/ f13 (230/232-.585/.595-114) and patriot heads. Thanks.

Duals won't hurt the cam, valve bounce and float will. You need enough spring to control the valve train.

PSI are great springs, but you need to find out the required seat value then compute through the lift to see if there is clearance to get the required seat value by shimming. You need the final installed height.
