Thought I'd shorten this up. Didn't find what I needed in the sticky.

Which LIM gasket set is the preferred choice--- GM, or Felpro? I know that 2nd design with aluminum carriers is the right type, but which brand tends to be better?

Do the intake manifold bolts have to be replaced, or are they ok to reuse if not otherwise damaged or corroded?

 

don't know why no one answered this felpro I would go with as the gm ones were known to fail ,another good thing to do is make sure nothing is warped so planeing everything at machine shop is smart,if the bolts are good reuse then if not replace them
