I just got a deal on some brand new, out of the box Trick Flow Twisted Wedge Alluminum heads. My engine is a 93 5.0 with the auto trans. So far it has a larger throttle body, full exhaust, and an air intake. With 115k miles on my engine now, will putting brand new heads on it kill the engine??? She still runs strong and blows no smoke. How much more HP and Torque can I expect to gain? How much lighter are they than my stock heads? Thanks for your time! Your conclusions will base my sale.
