im going to be putting a 220/220 .581 on 112 cam in my truck and was wondering about valve springs. ive seen a lot of horror stories with the comp 918's but have seen nothing but good on the pac springs. What do you guys think of the PAC 1518's for my setup? i put about 25k miles a year on my truck and dont really wanna change springs twice a year or even every year to be honest.

 

The pac 1518's should easily go to 100K on a cam like that. That's a top of the line beehive

 

alright thats good to hear. thanks
