Valve Spring Choice
Recently had a valve spring break while on a short Sunday cruise.
The car is a big block with a Schneider cam (256-2H), nothing special
in the motor build, just a replacement motor, by a PO in 1986. Not
many miles since then but I have put in new lifters, push rods,
and roller rockers. Probably enough history.
The springs that are in the motor are single. I've found similar, with
similar ratings butI would like to better understand the many different
choices available. Comp Beehive look interesting but is it worth the
higher price? Why do some run a 2 or 3 part spring? So I need for
advice, recommendation, and education.

You can just replace them. Beehives will get you better valve control at High RPM but your cam will not pull at high rpm anyway. Here is the correct beehive. http://www.compperformancegroupstore...e=EFIHemiValve
You will need all associated parts.
I would go with the Schneider dual spring and just replace them. Set up @ 1.800 installed height. Hope you broke in your new lifters correctly.

Thank you for the links, and for explaining the time induced age.
Makes good sense.
Hate to badger the point but why double springs over single? Maybe this is
motor 4.0 and well above me, but I am wondering about the many different
seat pressures too. Is this all RPM potential related?
