In order for GM to fit a 2.165" intake valve they had to tweak the valve
spacing. I believe the stands and the exhaust rockers fit but you'll need 8
offset GM intake rockers.

The LS3 rockers are only $10 each and the stands are $7.50 each. You can have brand new fully assembled LS3 heads ($630 for the pair) and the new rockers/stands for $725. Factor in what you can sell your existing heads for and the deal only gets sweeter.

I got mine from Pace about a month ago. I couldn't believe the price either.

Now the LS3 head has a D shaped exhaust port, correct? That is different from the L92 head and requires different headers doesn't it or am I wrong as usual lol

As far as I know the LS1,2,3,6 all share the same exhaust ports. L92 being the same as the LS3 aside from different intake valves (hollow vs. solid).

I know LS7 and LS9 are different but I'm pretty sure the rest are equal as far as exhaust ports go.

Someone correct me if I'm wrong, I'm fairly new here
