Re: 69 302 Header Recommendation?
Headers generally add 'high rpm horsepower', not low rpm torque. if you do install headers, and 'torque' is an issue for you, then you should keep the primary tubes on the small side (1-5/8" and no larger than 1-3/4" dia). PS> torque is generally not a strong point with the 302 (or any big bore, short stroke engine). long stroke engines (under square) generally delivers higher torque and lower high rpm power; Oversquare engines like the 302 deliver high rpm horsepower at the expense of low rpm torque. The Tri-Y design is as good as you will get for 'torque'...
