Comp Cams Xtreme Energy XE270HR
Purchased the Comp Cams Xtreme Energy XE270HR Cam for my '94 GT. I have the GT40P heads and upper/lower intake also. When installing my cam will i also need to change valve springs? Or can i just use the stock setup?

That cam was designed for 1.7 ratio rockers and you'll definitely need to upgrade the valve springs. This isn't the time to cheap out and reuse stock rockers/springs.

Yup, they'll work. Alternatively you could go for the beehive springs:

Call Comp and ask them what springs to use. You absolutely HAVE to upgrade your springs.
