I hope your not gonna run the 918 on that cam you just described.....did I read that wrong.
I wouldnt consider going over 590 lift with those, they are only good for 600 and you have things expanding and contracting in there.....might check that out. I could be wrong to! I did have a comp represenitive tell me not to run the 918's on a 581/588 cam.....so n e way I hope this helped you or keeps you from breaking something.
