One step warmer plug
Better gasket matched intake/heads, found some 1/16" gasket lips in there I did not like
Properly aligned valvetrain, jacked the rocker arms up .25", new pushrods
Valve cover oil leak
Version 2.0 of adaptor spacer for Holley twins on Edelbrock intake, preserving the dual plane all the way up to the carbs, delete the 4 hole and reduce the adaptor angle
Set of Quick Fuel 600's so I can see how another set behaves and swap the BJ/BK's in and out
PCV valve
Air filters to let it breath better
Reduce the stall on converter from 3100 to 2700/2800
The thing winds out really well albeit a bit lean, need more bottom end.
Thanks
