    Default New head on the Callaway turbo'd 535;pretty happy.

    Paul Burke built a new head for the 535. It has been on there for a few days now. Put everything back together with the ARP head studs torqued to 80ft/lbs on a Goetz head gasket with a few enlarged coolant passages. Keeping it reined in at 5lbs of boost while shaking it down for issues. It is very responsive; the boost shows up just under 2k rpms.

    Looking for intercooler and water/methanol injection solutions.
