I am planning to do my heads soon and was wondering which heads I should get. I was thinking AFR 165's but is that going to be too small for later use with a 331 setup? If so would AFR 185's be overkill on the 302 for now? Which one (if any) will complement my Cam choice or should I go with a difrent cam alltogether? should I upgrade my T/B and MAF (size suggestions) or is the stock ones fine for now? Thanks in advance for all of the help.
