I thought the Edelbrock Victor JR 426 Hemi heads were pretty nice.
Stem to guide clearance seemed a little loose which I guess I'd prefer to too tight.

The only thing I didn't care for was a few of the spark plug holes were tapped
a little bit roughly. A few plug changes will naturally chase the threads so it is no big deal,
but it seemed almost like the machine was running too fast, the tap needed
to be replaced, or something like that. But no big deal.

They're for a different engine and nobody has them in stock anyway, so I'll crawl back under my rock.
