im about to install my strup headers i bought from a fellow g35'er. im not sure what was suppose to be in the package. am i suppose to re-use my old gaskets or should i get new ones. is it ok to re-use old exhaust manifold gasket?

 

I would get new ones.

 

I've done quite a few sets of headers on VQ's. Always used the stock gasket. You'll be fine with the stock ones. Good luck though. Headers on these cars suck on the ground.
