Excelent heads so far. cam and heads make killer power 3k-(dont know yet because i havent pushed it that hard) but i smoke the tires in 2nd if i punch it from 3k. Thats with big heads, non optimal cam, and low compression ratio. Not to mention a 75mm tbody. I have a feeling the 180's would be killer heads on a nice n/a 306 with 10:1 compression and a good cam.5.0guy said:pro topline? those any good?
