i have a set of crane cams 99893 valve springs with titanium retainers for sale. springs are 1.460" OD and are good up to .600 lift. springs and retainers have around 800 miles on them. paid 330 for both asking 200.00 plus shipping

 

Any machining need to be done with those, or will they fit a stock LT1 head ok?

 

On a positive note these springs are rated (Max Nt Lift w/.060 Clear 0.710), same springs I'm using with my Crane GM847 cam and rated for well over 1.7 roller rockers. This is a good price for someone.

 

i want to say that they will fit without maching the head but iam not 100% sure. my heads had already had work done to them at the time i put the springs on. i did have to clearence the bodys on my crane gold 1.6 rockers so they wouldn't hit the retainers.
