MHS 4.6L / 5.4L 3V Freshen Up Package -

This is a great package for the budget minded ones. We realize some do not want to fork out the money for CNC ported heads as they are not necessary for every application. However, most 3V Heads now have close to or over 100K Miles which means worn out valve guides, leaky valve seals, carbon build up, ect. 

We can fix all those issues while improving performance. The answer is our Freshen Up Package. 
We start by disassembling the heads, thoroughly inspecting them for any possible damage, removing all oil galley plugs and freeze plugs, removing the old valve guides, deep cleaning them and bead blasting the ports and chambers to remove any additional carbon deposits. The heads are then moved over to our Seat and Guide area where our custom Bronze Guides are installed and honed to size. We then perform our Performance 4 Angle Valve Job. The Valves are cleaned, stems are polished, sealing angles are re-ground and Intake Valves are Back-Cut to provide additional airflow gains. The Heads are then surfaced on our CBN / PCD Surfacer and Assembled with our Viton Valve Stem Seals and your stock Valve Springs. Heads will also be assembled with new USA Made Brass Freeze Plugs and New Oil Gallery Plugs. 

Cylinder Heads are to be sent in with camshafts, lash adjusters and followers removed. If you would like to leave them in the cylinder heads, we can clean all the parts, polish up the camshafts and re-install everything for an additional cost. You will also have the option for us to install new OEM Lash Adjusters which is also a good idea.
