Yeah, the AFR's are a bit more, and they do sell them bare.... Have you looked at the Patriot Performance heads? They even made one for Chevy, think it's like a 325 runner???? They're also available bare or assembled....

AFR part no. 3050-1 is the 305 cc head as cast with no parts....

As for the header fitment, it would depend on how much the ports are raised and how much room there is with stock configuration ports... I've seldom used a set of "store bought" headers that didn't need at least some minor mods to fit.... Actually prefer buying the flanges and collectors, a bunch of mandrel bent tubing, and building my own..... More time consuming, but if it's done right you'll end up with a better set of headers that are sized and fit specifically to the car....
