Thread: 1.9 terra yella roller rockers

wht valve spring do you guys suggest for the yella terra roller rockers 1.9 ratio and wht are your thought on 1.95 any good or not reliable im leaning toward 1.9 and possible head porting next year thanks

105's

105's sounds like the right thing from what i've read. If I were you, i'd go all out with the 1.95's

ok so i have anothe quick question are cams better than rocker for power and do you need to upgrade valve springs for a cam

You will get a lot more power out of a cam, but is a lot of work and you have to know what you are doing to install it.

if i were doing this id get crow cams 130s and rev the crap out of it.

^^Agreed. 6500 rpm's ftw

L76 valve springs
