There is a design difference between beehive and conical springs. Read this link before making your decision.

I run PAC 1427 conicals in my SBF 302 with N351 heads. They are right below the 1409s you are looking at. BB Chevy stock elim springs. They are 200/500 at 1.85 with my .597 lift cam. 6500 in the 1/8 all day.

BTW I'm solid roller all the way. If you are stock, make sure the springs you choose are allowed.
