First you compression is about 10.25 so 150 to 160 is not that bad with a 246 deg cam.
did you check you cam degree again after picking the +2 deg keyway?
always check check recheck

next 57s are way way too cold for that engine go with 61's or even 63's
just go to your local parts store and grab a set of RC12YC and put in to try!
you are sure your firing order is correct?? seen a guy swap 6 and 8 and is power was down 40% and they are so far appart in the firing order not mush ill effects just two cold holes! and of course 5 and 7 are easy to mix up! :-)


On second thought you should be around 180 so maybe you cam is installed retarded??
