i plan on upgrading my valve train before i buy my 35r kit. highest i plan to rev is 8k max, but im sure 3/4 of the time ill rev it to 7500 (i shift @ 7500 now) would the single valve springs be just dandy even if i take it to 8k?

i know a lot of people say go with the dual, then others say the single are just as good etc.

 

Singles will be fine for what your looking for.

 

alright thanks.. whats the max persay i could rev these too (singles)

 

i broke a single supertech,got duals now go with the duals.

 

is the install different from the singles to the duals?

 

install not different but, you gonna need thinner valve stem seals.

I think the Ferrea dual are drop in as they come with a bottom spring retainer.
I haven't installed mine but was told they will work just fine.

 

the install is different you have 2 spring to compress same method yet two springs to compress that can out to mutch pressure on your valve terrain if not used to the full potential of the dual spring setup.

 

dont see how a single would break unless installed wrong or really overreving to 9k+. max ill go on it is 8k so i think singles would fit my setup perfect
