Default Looking for opinions. Stock LS3 top end on LY6 or 243's with ported FAST 92?

Looking for a little input. I'm picking up a 2009 LY6 and it has the stock LS3 heads and a truck manifold. Should I keep those heads and buy an LS3 intake or go swap over my 243's and ported FAST 92 from my LS1? All motor build for now but will eventually go sheet metal intake for a cheap little ON3 build. Thanks in advance!

I'll stay on the rectangular heads (LS3) and get a cam from a good vendor on here. Come out cheaper and make more power!!

Keep the LS3 heads you already own! We can help with a intake to meet your goals & can even help spec a camshaft package to go with it. I'll even mill the heads for ya if you want before you put them on!

Give us a call & we can discuss LS3 heads camshaft options & what milling can match them!
