I will be installing brand new old stock GT40P heads with upgraded springs next week, I have a 94 Cobra intake, highflow catted midpipe, BBK ceramic coated shorty headers, ASP underdrive pullies, K&N airfilter with removed silencer, MAC flowpaths and bumped timing. I also have a Kirban adjustable fuel pressure regulator with a fuel pressure guage on the shraeder valve. I am leaving the stock cam in at this time. Do you think I will need a dyno tune to make it run right? there are no shops anywhere around me. Thanks in advance.
