He says in a post a few down from the top that they are EQ heads. Wouldn't those have enough clearance? I'd like to think so since they are sold as a "performance upgrade", but I am not familiar with them enough to know.
I overlooked it. Thanks for the correction. I'm not positive they'd handle that much lift. I didn't measure mine since I had to have them machined for double valve springs anyway but for some reason max lift of .525 comes to mind. At .550-.560 lift I'd definitely measure them.
Their not really considered a high perf head like a Edelbrock. More of just a magnum replacement with better ports for more flow.
