Valve job on os valves

what cam are you running, I have a 270 redone cam I picked up when I bought a spare engine, came with a rebuilt head (spare ) and a the cam .
You talking to me? I've talked about this build all over the place, I'm sure some here are "blue in the face" from hearing about it.
But back to talking about heads, it was pretty much a moot point on the slant 6 head being as how I brought them oversized valves from the get go, so the machine shop knew they would be cutting my seats oversized (and replacing the exhausts anyway regardless of save ability of the originals as put in by the factory.
Add in my oop'ses from being a novice head porter, where I bumped the original seats so many times it was a foregone conclusion, they had alot of seat cutting to do.
But back up for a minute to when they did both those "302" heads and my "Ready out of the box" EQ heads (that weren't) that I got for my Durango the machine shop went on and on about how Chrysler couldn't cut a true and concentric seat at the factory "to save their lives". Even though the aftermarket EQ heads weren't factory heads they had the same complaint about those as the mid 80s "302" heads they did for me.
