Selling a set of ProMAXX 180cc Aluminum heads, angle plug from an abandoned project. Comes with pushrod guide plates and studs. These are a significant performance upgrade for 305, 350, 355 SBC. Half price - asking $600 plus shipping. For $700 plus shipping, I'll throw in the hardened pushrods and Comp Cams 1.6 roller tip rockers.

What springs are on these? And what's your location?

Sorry brother, I already sold them . I’ll get the post updated.
