Hey yall im getting a 2.5" y-pipe and 3" exhaust put in and i want to do heads over the summer- Are heads really that important to a nitrous vehicle? I would be doing 3-way valve job, port polish, 1.6 roller rockers, Port match to intake manifold, ARP head studs, 2.02 / 1.6 valves- would this help out on the nitrous set-up? i know it would benefit N/A greatly but are they that important?

 

That's the beauty of a a small $$ investment in n2o, best bang for the buck. Unless going pretty big with a nitrous shot, these mods really are indifferent, imo. Yes may help in n/a applications, but certainly not needed for the spray on normal street/strip size shots.
