Caution on the Trick Flows. They make the most HP for a street head, but the
wedge design is said to screw up the valve train geometry and result in problems
w/valve guides, noise, & premature wear. Go w/Edelbrocks--best quality. You
small valves (1.9 & 1.6) so you won't have to notch your pistons. The 2.02s are
big, and give HP while taking away low-end torque. And torque is the "funnest"
about a Tiger. It will appear once you ditch the 288 rear end gears.
Also, aluminum heads allow more compession w/o knock. Something about the
of the metal.
UPS says mine will be here next Tuesday. Also, I was advised to use graphite
Edelbrock has a web site where you can sign up for a free catalog. Good one,
