Posted 11/12/08 10:50 AM Share Posted 11/12/08 10:50 AM there seems to be a opinion that if your cars a BA you must do your valve springs first before you do any mods which I find kinda funny. The springs can start have trouble anywhere from stock to 350rwkws depending on other mods. Do your mods first and get a tune, if you have trouble with the springs then get it changed. Valve float can be easily seen in a Dyno graph. Link to comment Share on other sites More sharing options...

I have a full 4 " system though.I dare say that if I was only running the stock dump with just a cat that I would probably be having some valve float problems at my power levels.I have some Nizpro springs at the ready if I need them but im probably gonna be ok with the exhaust as it is...
