The ported aluminum 4v heads are coming off, so I just ordered a nice set of cast iron 2v heads... Less valves to rotate means less rotational mass... Also upgrading to a 7.8" rear like the v6's have... Less drivetrain loss, ftw...

I have some stock 2V head you could trade for. Not cast iron, but still a fair trade in my eyes :-)
