i am planning on replacing valvesprings and retainers with rev springs and retainers is changing the valves a necessity and if it is wut else needs to be done

 

you might as well get the valves to compliment the springs and retainers, don't forget to change the valve stem seals

 

Not to thread jack, but do you guys think that supertech springs/retainers would be that much better than just getting ITR springs/retainers. Its like 200 bucks less. So I could get valves along with it, if needs be and still be in the clear. Only gonna rev to around 8500 and it would be LSVTEC

 

Valves are expensive, y0! No, you don't necessarily need to change the valves

 

Get the head the 3 angle valve job and make sure it's straight and not warp.

 

supertech's are a better than itr, pm earl he sells them

 

Ya I realize they are probably better lol, but are they worth it, thats the question
