Alright, so I've just been searching through the threads, and it looks like I might've wasted some money on a set of 516 heads...apparently the general consensus is that they don't really do any favors for making power. They've been messed with a little, and require some port finishing to smooth things up a bit...but I figured it would've been an OK deal for keeping the compression up in a 383 as long as I put some bigger valves in them and worked on the transitions a little.
To the guys out there running a 383, what say you for these heads? Are they OK for a street/strip 383 up to 5500 or so? Or should I turn them in for scrap?
If they are worth salvaging, I planned on dropping in the larger valves and working the ports a little bit...any worthwhile commentary?
