Which springs do you prefer?

for 150+ship you can have the 853 heads they are on right now haha.

What would that do for me? HP Dif.

you don't want those heads....may give you a lil more compression....but not worth the time to put them on

actually it will give you less compression....but for 150 complete with 918 springs they are a good set of heads to do some porting/milling and massaging

aren't 853's a small CC then the 317's....thought the 317's were like 72cc and the 853's were 66cc....i'm prob wrong...just curious

853s=67cc

853s=67cc

damn 1 off lol....then it would raise compression if the 853's are a smaller combustion chamber, not by much but it would do it

So any HP dif?
