vortec header question
hey guys i have an lb9 car with Flowtech 31102FLT headers (saw no power increase by the way) i have come into a set of vortec heads and plan to have a 350 built to with them and use the TIPS big mouth system my question is will my headers still work with the vortec heads or do i have to replace them?

Re: vortec header question
Your TPIS intake will not work with Vortec heads. You need the Vortec TPI intake from Scoggin Dickey.
Yes your headers will fit fine.
