Hope this isn't a repete

Will the rockers and stands from other LS motors fit the LS3 heads ????

I want to upgrade with the rebuild of the LQ4

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.

Needs LS3 rocker stands also.

Intake rockers 12569167 x8
LS3 Rocker stands 12600936 x2

Well that kills that idea

I was going to get the LS3 heads and swap over the rockers.......guess i'll need to find a pair of used complete (good) heads


Thanks

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.

Where can you get the heads for that price? I checked with my dealer and the heads cost them 393.00 each, but on backorder I was told.

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

OK.... so if I get the heads from Pace $650....get 8 intake rockers @ $80...and get ???how many stands ?? 8 ?? @ $7.50.....

Looking now

2 stands. 1 per head

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

MX6.0

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
