289/302 aluminum heads question....
I found these heads on Ebay...
http://cgi.ebay.com/ebaymotors/Ford-...#ht_710wt_1165
I am looking to do a short term budget rebuild on my 289 short block. Currently I have factory heads. I believe they have 53cc combustion chambers and the aluminum heads here have 64cc. What pistons should I use so that I don't lose compression? What is the highest ratio I can go using 87 octane fuel. I plan to use a competition 268H cam, HIPO manifolds, aluminum intake, and holley 650 carb.

Not sure, haven't heard anything about them. But I'd be skeptical at that price, since good used heads are usually $300-400 each give or take.
As far as c/r, it depends on the cam and combustion quality, ignition system, bunch of stuff. 2 engines with the same compression on the same fuel, 1 might be fine and the other melts. That said, with your setup 9 or 9.5:1 should be fine. Somewhere in that ballpark.

Been discussed before a while ago, no one is really sure what they are

i find it very funny to mention proform and AFR in the same sentence *g*
"If you are looking for a race grade head that is comparable to Edelbrock, Dart, Trick Flow, Pro Comp or AFR at a fraction of the price look no farther then these. The features of these are as follows" ...

I agree with everyone! You get what you pay for, I am scrapping this idea!
