Mopar Action SB head article

My 85 318 has Magnum ports and chambers with LA rocker gear....very nice combo. They can be ported to flow with any standard intake/exhaust head out there!
These were the same basic heads available from 85-91 on all the 5.2's and 5.9's!

P.S. Mshred, they used a set of second hand Super Stock ported Mopar Performance Magnum R/T heads for that engine. It was a later model roller 318 block bored .030" over with 10.44 comp and a 340 crank that was hand massaged (knife edged and cleaned up, lightened some). They used a Comp solid flat tappet cam with 247 @ .050", HS 1.7 and Crane 1.6 rockers yeilding .622" intake and .597" exhaust. It made 477 hp and 427 tq on pump gas. Very stout and it was still climbing at 6500 rpm. That was the cut-off for the contest. It would have probably made about 482 or so at 7000 rpm.
