This is is not drag racing specific, do a little research in the GEN III ENGINE section. Also to answer your question is yes they will fit, IMO they are good for no more then a C5 Z06 Camshaft.

Welcome to the Forum.

No issue on the wrong section.

I did understand the question and from what was said. It is a common question but to be honest, to do this work you should be looking at something like either a Patriot Dual Gold Spring w/ Titanium Retainers or a Beehive replacement with Stock Steel retainers. PAC is a company people like to use and makes good stuff.

I currently run Comp Cam 918's and no issues with either version, but some have had springs break in the past.

Well I run the Dual Golds with the MS4 on my SS but the question was for a friend thats putting a stock LS1 with stock cam in a Nissan truck and the motor he bought needs valve springs and he found a set cheap off a vette and was wondering if they would work... Sorry if I came across the wrong way but 00blacka4 guy that posted on my comment seemed like he was trying to make someone look stupid... I mean everyone knows a LS6 head is not a LS1 head.. lol

Used springs are very Iffy IMO. I would have him buy new stock replacements.
