FIRST AND FOREMOST!

Dakota R/T & Durango R/T trucks DID NOT come from the factory with these heads! They have standard Magnum heads, a different cam and different computer configuration than standard trucks.

Now:

Special hydraulic pushrods
Designed to allow the use of magnum heads and
standard magnum rockers on standard 1967-91
"A" short block/engines.
5007477 Magnum head on standard "A" block-set of 16
(7.625") $38.50

This is from Moparts Racing

Make sure your lifters are AMC style lifters. If they have the little holes in the cups to let oil pass throught to the pushrods and eventually to the rockers. I know the last set of CompCAMS lifters I bought had the holes as well as the same part number for an AMC.
