GT40 heads & spring upgrade help

jaye1955 · Sep 8, 2011

I have a 1971 302 that I'm putting the GT40 heads on, I installed Trick Flow Specialties TFS-2500100 - Trick Flow® Valve Spring Upgrade Kits, and pedestal roller rockers; my question will these springs be too stiff or strong for my stock cam in the 71 302. My plans are to use the stock cam.
Thanks in advance

Just give trick flow a call. The number is on their website.

I have that same kit installed on my heads, but mine is a 1988 HO roller engine with an ISKY cam in it. If that were my engine, I personnaly would not feel comfortable with those springs on a stock flat tappet camsaft.
