need to raise compression w/o new pistons

Starting with the cylinder heads,you will need to have them milled .050 inches to get the compression up.You will need 2.02 inch intake valves with the intake and exhaust bowls opened up to the valve seats and ported out to the gaskets with a good three angle valve job.Use Mopar 284/284 degrees .484-.484 inch lift cam package #P4529958 with valve springs #P4120249,along with 1.6 ratio adjustable rocker arms#P4529692 and there special pushrods for adjustable rockers #P4529556.Next Mopar single plane manifold #P4452891,with Holly 750 cfm Double Pumper carb#0-4779.Mke sure to have the intake milled to match the heads as the geometry will be different.Use wind tray kit #P4529790 and HD oil pump #P4286589. This set up will be good for 380+ horsepower according to Dick landy.Hope this helps.
