just wondering if a set of mac shorties bolted up to a set of ported E7 or GT40 heads will work fine? will flow be decent? any bottlenecks?
i guess i already know they will be fine on ported E7's just not postive on GT40s
reason i ask is bc i read a post of someones aftermarket head choice and the exhaust ports were not much better than stock. someone suggested a different set of headers other than what he already had.
thanks
