    Hey guys. I picked up some ported/polished L26 heads which I'm going to be putting together as soon as I can. I'm going to be getting 1.95 roller rockers, and I am unsure which valve springs to buy. Some people say LS6 springs, some say L76 springs. Which ones do I need?

    Thanks!

    How about Crow #105's...best spring out of the 3.

    IMO, if your set on one of your choices...get the #90 LS6 springs...I ran those with my XP setup and had revved it around 6500...with no issues of valve float

    Assuming you're not planning on revving that high, the L76 springs would do the job with less stress on the timing chain, and they're cheaper.

    LS6 springs are pretty cheap too, especially on EBay...I got all 16 of mine for like $50 shipped.

    That's about what ZSPOT sells them for and they're coming from a Dealer. At least you can be sure your getting what you paid for.
