valley cover for boosted 427 had a quick question for you boosted guys, im about to assemble my 427 twin turbo motor and was wondering about the valley cover. i have a standard LS1 valley cover (non ventilated)and was wondering if i would gain any advantage of changing it out with an LS6 valley cover (vented)? i will be installing a Mighty mouse catch can that will be vented from valve cover but if the added ventilation from the valley cover is worth the change then i am all for it? any opinions?
