Default Valve springs

Hi. am back in a C5 only a Z this time. haven t had a C5 for 10 yrs. but i love them

Haven't done mine -- but then I don't have a Z06 -- but the name I read far more often than any other is PAC Racing. Not inexpensive, but the good stuff never is.

pac makes really good springs, well worth the money in my opinion... if you are going to stay with the stock or a mild to medium cam with not a lot of lift or aggressive lobes then stick with a beehive

That's a huge cam - is that going into a 5.7L or something bigger?

You going to need something like Comp Cam #26926 springs with 159 lbs seat load @ 1.835" height, 448 lbs @ max lift of 0.675"
