heads/cam

[89CobraGT]

I was wondering if a decent set of aftermarket heads will have a dramatic increase over my ported/polished 351 heads and if I do decide to get some new heads do I need to change my cam I have a B303 ? or are most heads compatible I was looking at these freedom series from 5.0 resto http://www.latemodelrestoration.com/iwwida.pvx?;item?item_no=PAT-1102 1&comp=LRS Does anyone have an opinion on these?? sorry for the long post thanks for any replies

Kind of hard to know what difference other heads will make without knowing what kind of power you are making with your current setup. Any dyno numbers or track times?

grey5.obeast has a set on his car. pm him and ask him what he thinks. and just about any aftermarket head will out flow a cst iron head.
