Got lazy and never took the pressure off my valve springs before I stored my bogger for the winter, it's been setting since October, should I replace the valve springs before I run it this year or will it be safe to run them they way they are
if your worried then get a spring pressure checker and check them, they make some that can be used without pulling springs. I went a year and a half with mine just setting and they seemed fine. There's a couple different trains of though about this subject, some say springs wear out buy cycleing (opeining and closing) and are fine being let compressed, the others think you have to remove the pressure or they'll get week. ==shrug
I would just roll it over so a different spring compresses
I'd say you'd be ok. Cars sit on springs all the time, plus cars sit for years without having the valve springs go bad

arent car springs a little different then what you would find in a performance race motor
Sure it's bigger, the principal would be close to the same I would think. The spring is holding compression either way.
I Google it, some people did it, some didnt. Best reason I could find to do it is to seal the chambers so moisture and mice couldn't get in.

Even on a performance race motor....
what type of cam do you have? (not brand of cam)
your 99% fine bud, even though it's a better idea to fire it up or roll it to keep things oiled inside sitting for a few months rarely hurts the springs, i've had a 600 lift sbc sit for 4 months and never even worried about it, ran fine for a couple years after that too

roller
Running fine and at max performance are two different things. I'm sure it will still run but they must recommend it for a reason. I'd spot check a couple of your springs with a spring tester to see if it's still in specs if you think it might be a issue.

solid lift roller cams are hard on springs, because of the spring pressure that you run on them. spring do get weak.
My solid roller went 3 winters with never being backed off. Took motor in to be freshened and springs tested the same as when they were new. That's a .750 lift spring
