Took some time off but she's finally back.
New head, new cams, new fuel.
Tested a head from the infamous Rich Stratton, that was used on his 2.4 build.
Long story short, the head sucked for NA, was poorly ported, had the wrong cam caps attached etc. Ended up losing 30whp over the previous head.
New head will be on this weekend and will start the large cam testing.
