Any recommendations for 350 V8 headers
I have exhaust manifolds right now, they are not sealing well as they are old / corroded - theyre getting noisier and I think its time to change them out and headers might be the way to go. Are there any recommendations that are foolproof and drop in easily that folks have used. Summit has such a huge selection I'd rather listen to some of the experts here than wade through hundreds of different options.

Re: Any recommendations for 350 V8 headers
Last year I installed Hedmann 69230 headers from Summit in my 1980 K10 Suburban and they fit fantastic. Can't say enough good things about how easily they installed, and keep in mind this is a 4x4 so the front driveshaft can occasionally be an issue with headers. Routing around the automatic linkage took a bit of thinking, but not a huge problem. I have no clue how things might be with the z-bar of a manual.
As well as they fit, though, I'm not convinced I made the right choice by installing headers at all. I've avoided them for decades, and now I remember why I hated my first set way back in the day: 1) Accessing the spark plugs is a pain. The 69230 doesn't require shorty plugs, which is nice, but only a few can be installed with a socket. Two or three require a stubby wrench to get tight. 2) Periodically having to re-tighten and occasionally even re-install the collector bolts is a pain. 3) My butt dyno reports no extra power over factory, which is disappointing. Overall, I'd have been happier long term staying with the factory cast iron logs.
