I need some heads, what kind?

[Agent_4573]

Okay so i blew a head gasket while overheating one day and i think one of the heads is cracked. I'm having them tested now and if one is cracked, im gonna go ahead and buy a set of performance heads for the car. Now im on a VERY limited budget (as in the new heads are gonna hafta be financed threw a loan at the bank). With this in mind, I can't really go over 1000 dollars and the farther under that i go the better. I was thinking a set of gt40p heads, ported and polished and if possible used. The 1000 dollars has to be for everything though, including new gaskets, new head bolts, new spark plugs if nessacary, and every other nickel and dime thing that could be involved with a head install. I will be installing them at home with some help so i don't need to include mechanics charges. So your opinions on where and what kind i should buy.....
