LS3/L92 heads with SBC/BBC valve Springs
Is anyone running older roller SBC/BBC valve springs on LS3/L92 Heads?
Is there any difference??? I've been looking at specs and it appears that there is a large variety for sbc/bbc and very little for ls motors.
The specs appear to be almost identical...why can/can't we run these???
HELP!!???

I'm not talking about "cheaping out" on valve springs, what I'm talking about is parts that appear to be directly compatible, install height, inner/outer diameter and pressures. Why are these basically the same and they cost up to 20x higher for the LS motors????
This seems odd, even when you look at headers...why is a set of BBC 2" or 2+1/8" 1/2 the price of LS 2" headers?
Comments??

There are lots of springs for 250.00 that will work on your heads...why not use them?
You can use any spring that fits within installed height/coil bind limits. The diameter of the sbc and bbc springs is often a problem with ls heads ie they are larger in diameter than ls springs. There is nothing special about ls springs. I would make sure the locks worked ok cause the stem is a different size. I recently used some lsx heads on a build as they are machined for a larger diameter spring than other factory ls heads. Many aftermarket heads have more meat for larger springs also.
