Help I need heads!!

[SmokinStangGT]

Yea i didnt know how big the heads were, and i blew both head gaskets on the inside of the head gasket cylinder holes, and water jacket holes cracked and were letting in coolent. I have the stock upper an lower but both ported a bit and a 65mm t.b. The heads that the roush had i wanted to have better flow because i am going to bolt on the holley upper and lower in a month or so. I dont have the money to throw in the aluminum heads and replace the rockers, etc.. I have a small port job on the heads, and i wanted the bigger sized valves. Is it worth it to stick in the roush or try the heads again with some really good gaskets? The gaskets had to have been my problem im guessing but dont know if i should get the heads, i want them jsut so i have fresh heads but is it worth it??? -Thanks Everyone
