302 heads, cast iron or aluminum?

66StangBoy · #1 (**permalink**) 02-23-2003, 12:15 PM

I'm in the process of building a slightly beefy street 302 for my 66 Mustang, I've got an Edelbrock Performer Intake waiting for my block to be ready, and I've already decided on pistons (hyper-eutectic) and a cam (CompCams 268H).

I've been trying to get a feel for some decent heads. This engine will never be raced more than possibly on a city street (i.e. almost never, and never on a track). Anyone have any particular preferences? I've been toying around with the idea of some Edelbrock Performer Aluminum heads, but the World Products Windsor Jr. or Roush 200 cast iron heads seem pretty nice as well, and seem to be a fair bit less, as well as some rebuilt E7TE heads... Comments? Sugestions? Any help would be appreciated.

Thanks,
Ryan

I WOULD GO WITH THE CAST IRON

I went thru the heads on my last engine. They were 68 302 4V heads with the small chambers. I put in 1.84/1.54 valves, hard seats, screw in studs, new guides. By the time I was done, I had a few $$$ in them.

If I was going to run iron heads again, I'd take a serious look at <a href="http://www.powerheads.com." target="_blank">www.powerheads.com.</a>

And the Roush heads you mentioned are pretty nice too. Just check the exhaust runners on them before you buy. Some of the early ones made it to market with a flaw that impacted exhaust flow quite a bit. A core shift problem I think. Also heard that they took care of it later.

If its just a 302 thats going to be street driven, i would just stick with the stock heads. YOu will be more satisfied with the low end torque they produce. Being the fact that there is only a measly 302 cubic inches, it wont hurt quite so much. I have edelbrocks heads on my car with the 2.02 intake valves, and i could feel the loss of torque around town. Afermarket heads are made to benefit upper rpm usage, but if you're never going to use it, why spend the money on buying those heads.

mustang66maniac is right on the money <img src="graemlins/mwink.gif" border="0" alt="[mwink]" /> keep the stock heads with the intake and cam you have expensive heads would really be a waste. <img src="graemlins/mwink.gif" border="0" alt="[mwink]" />
