If you're going to P&P and mill the head, you might as well get a set of aftermarket cams to fully take advantage of the larger ports and higher flow rates your head will have when the work is all done.

If you can find yourself the magical b20 head it would be better. comes with the bigger 33mm intake valves just like Vtec heads i believe and has some port work from factory with a lil more aggressive cam profile then the regualr b20s out here. Im just not sure on the Stamp number of the head.. I think it's stamped P8R..


Look i found a link for ya..

In a nutshell, it is a VTEC head without the VTEC. :thumb:
