I considered the 3 sim manifold upgrade as something I might do in the future…mainly wanted this rebuild to be successful before doing other mods.

However looking at dyno sheets of the 3 sim mod I’m not sure the area under the torque curve is higher except at high rpm so I’m not sure it’s worth it.

The head porting really woke up the engine especially after 5k, pulls to 7200 rpm hard now where it used to soften around 6200 or so…still not sure the manifold upgrade is worth the trouble.

The valve cover was painted red crinkle after painting with flat black plastic paint to prep the surface for it, stainless Allen head capscrews were the finishing touch.
