302 or 351 heads?
I have a '72 Bronco with a mild 302. In the future I want to stroke it to a 347 cuz it will be less trouble than going to a 351.
This thing is strictly for off road and I want mostly torque but hp also. The stock heads are 1972 non-adjustable stud mount. I don't know the cc's or the valve sizes. I have done a little porting on these heads and I think it helped out alot, but I don't know if these will be enough for a 347.
I have a set of 351 heads that came off an early 80's police car. I don't know the casting numbers but I thought they might be better than the stock heads. These have pedestle rockers. The last I heard was that by the 80's all 302 and 351 heads were pretty much the same and that only the late 60's early 70's 351 heads were the ones to look for.
I would like to know because around here the old timers still tell you to put 351 heads on a 302 regardless of the year.
I think the E7TE heads were supposed to be the best stock head short of a GT40.

I've gotten alot of hype from my local speed shop, that the World products Windsor and Windsor JR iron heads are cheaper and flow better than GT 40 heads. I just picked up a magazine that did a dyno comparison w/ 306 vs 347 w/ identical parts you might want to look at. The Magazine is 5.0 Mustang & Super Fords April 2001.

[font size="1" color="#FF0000"]LAST EDITED ON 05-Mar-01 AT 12:37 PM (EST)[/font][p]If your bronco is lifted a 351w should fit OK. Then you could
buy some aftermarket aluminum heads.
