Looking for 360 heads j/x?

Bigger chamber of the X O U J heads and you will lose a lot of compression.

Yes, but flow trumps compression. #-o


You will still get a performance increase, but will be more efficient if you bump up your compression. :???:


If you get 10.5 pistons for a 318, and then use a 340/360 head, you will end up at 9.2 compression. Perfect for a street engine on pump gas.... :glasses7:
