is .524 to .541 too much for the srpings? since i have no clue what the spring pressure is or what they will take i want it to be a s close as possible to what is in there now (.524) I thank all of you for the advive you have given me. I agree that a different cam would be better like the XE would be a great cam or the 275DEH. I think that the .536 lift is max for me like I always say better safe then sorry
