I am look to change my valve train don't know what i need?

Dual or single?

I am just doing stock size. What would be my best option? I also doing valve but stock size. I want to keep the machine work a cheap as possiable. So no valve jobs or PNP.

 

if you don't know, then you should not be doing it in the first place

 

i know i need retainer valves springs to complete my change over. Why do you have to try and rip me up i am just asking a question. Well i have to rebuild my engine i have 150,000km on my car. well jim wolf only sells single and Brian Crower BC come single. I just saw a posting with duel and wanted to know the main gains and is it work it for me b/c i am just donig stock sizes. Be i don't want to put this twin turbo kit on it and them blow up

 

Someone translate. Are you talking about dual valve springs? What's your question on retainers? What does all this have to do with a twin turbo kit? A twin turbo does NOT give your engine higher revving capability, nor does it keep making power as you increase RPMs. Did you add cams and/or change anything else that will allow your engine to rev higher and make power there?
