hey man what do you think of 308 heads? im thinking if they flow the same as an x head on the intake port but have a better exhaust port, they might might make a decent cheap iron head for a 340 thats going to run nitrous..what are your thoughts on that? does it make sense to go from x to 308 for that reason, IF it can be done cheaply? I know its opinion, but im interested in yours or anyone elses for that matter
