I would like information about Ford Windsor heads. I plan to acquire and rebuild a junkyard special 302. How can I ID the block/heads with casting #'s? Is there a website or easily attainable book with this information?
Is there a big performance difference in 2 barrel and 4 barrel heads? How high of a camshaft lift can stock heads handle?
Most everyone trash talks the stock 5.0 E7's. I do not have the budget to acquire aftermarket aluminum heads. Are the E7's superior or comparable to heads from a 1970's F150 pickup truck?
E5 castings are good as well, can be found on 302 and 351HO pickups.
Casting numbers denote decade, year, line.
C=60's, D=80's, e=80's,F=90's
1=1, and so on
T=truck, z=Mustang
E7TE are 1987 truck castings, and that is what the stock 5.0 heads are.
I am limited to the supply of the local boneyards, which are overflowing with rust rotten late 70's pickups. Finding a 302 HO, Explorer, or 351W is close to an impossibility. Any 302 castings to stay away from, or all pretty much comparable?
Using the stock pedestal rockers, new valve springs, and notched flat top pistons, how high of a camshaft lift can stock heads handle? The reason I ask is because I like the sound of a longer duration cam, but I see lifts of .500, .542, and .589".
I love the sound of the GT500 Eleanor in the movie "Gone in 60 Seconds". I desire the evil rumble of Alternative Automotive Cobra, Click here to see and hear this awesome car. Any cam suggestions to create a junkyard 302 with more bark than bite? Can an evil rumble be created with a small cam, factory shortie headers and 2 1/2" pipes, or would long headers, big cam, and 3" exhaust be required to create the sinister lope?

close, but not quite right....
AZ=Galexie, LTD, Crown Vic
DZ=Falcon, Maverick
OZ=Fairlane, Torino
SZ=Thunderbird
TZ=Truck
ZZ=Mustang.
Do not use a casting number as a part number, since there are a few odd codes in them. All prefixes in casting numbers end with an E...IE F3ZE or C5OE. The middle number is the base number, this tells you the type of part that it is...1007 is a wheel and 6049 is a cylinder head (also the first digit tells you where it is on the car). The sufix of the casting number tells you which design it is...A is first, B is second.....

Im a Knob to the cumputer tuned muscle cars but decided to get my feet wet with a stock 88 5.0
Good topic and info all. I also would like to add a set of GT40 heads to my motor. I have been reading alittle here about finding some Late Model 5.0 exploror's or pick up trucks that have the GT40 heads on them but I need alittle more info on the year or model (ie eddy bower) and I take it they are the Iron heads?
I think after I read this thread 10 more times I will have the casting # end figured out
Thanks again for the topic and any feedback

Just remember that if you get the GT40P heads you need to change to the header for those heads - the E7 stock headers won't work.
