I'm currently building a 427 bbc for my '74. I already have the short block assembled. My question is, i have a set of o49 oval ports that i took to the local machine shop to ask the guy wat he would recommend doing to the heads to get some decent power and he told me to just put some bigger valves in them and they would work just fine that it wouldn't be worth porting them but he could still do it if i wanted to. Should i still port them or not wat do yall think?
