i have a MR and have just the bolt on with a boos controller and i want to have more top end so im looking at hks 264s or 272s i heard that ytou need to replace the vavle springs if you go to with the 272s what should i do????????????

 

You dont need to replace the valve springs if you go with 272's the only thing you should do with the cams is headstuds and a fuel pump. I have 272's with no head studs and I have no problems (Knock on Wood).

 

no springs needed

 

Drop the 272's in. You will be fine. No need for the extras.

 

thanks..anyone know where in cali i could get it tuned after all of this???????
