Ok so I gotta guy wanting to sell me some e7 heads that have been ported and polished with dual trickflow springs and valves, they have 1200 miles on them, he also said they havent been ported to well but the gasket and all that matched up still and that they just did the intake side. He also had a 93 cobra cam he's throw in and that i could get them all for $200. So you think this a good deal? Also would these heads and cam make a good combo? And do you think they's perfom like gt40p's? Thanks.
