Hi!
I'm all twisted up right now trying to decide what head I should put on my 270 GMC straight six. It's only going to be a mild street rod engine; 1940 Chevy Coupe, dual carbs, 3/4 race cam, no salt flat/ top speed car by any means.
Option 1 is either one of GMC's big port heads, being the 270 "H" head (2193417) or 302 "D" head (2193983). Option 2 is just leaving the origional small port head on it now (2194819).
I'm willing to spend the money for a new head if it's worth it. I've got a line on a 302 "D" head nearby. I've gotten mixed answers from everyone I've talked to so far ranging from "It's a must for any power!" to "it's a gas guzzeling waste of money!" so I thought I'd run it past the experts before I start throwing money away!
Is it worth it power wise and gas consumption wise?
Thanks a bunch! Great website!
Pete
