Even the head bolts off that engine are much better than the head bolts off older engines.
Before you sink money into the heads for valve grinding and milling, evaluate the "core shift" and see if you have good candidates. You are likely OK, but to be sure check them out.

Interesting about the self-aligning rockers. So, stock-stamped GM rockers will not work with these heads? How is that determined? (again...interesting point).
On the current heads on my truck (and the spare '72 heads I have in the basement) the stamped stock rockers have a machined separate 'pivot washer' in them that resides between the rocker and the 3/8" rocker arm bolt.
Are these self-aligning or what is the difference in these vs. others?...if any?
As for sinking money into these heads....no worries....my expectations from all of this are absolutely average at best. These are high production, low power, super average, low cost heads used on thousands of crate engines...nothing more.

The root of the posting here is the whole idea of picking up a set of useable SBC 1.94" 'rainy day' heads for $50...and remember...that's $40 U.S.D...lol!
The only thing I might do a rainy Saturday morning is gasket match them...that's probably about it.
All Good
