Hyup, blue, aluminum, right out of the catalog, no banana grooves.

1999 Mopar Performance, page66, Kit P4529692 includes everything. says including logos...... mine came with out those,lol
I also bought the hold-down kit P5249712
Why?

I had a set a long time ago and sold them with a set of heads and of course I regretted it a few years later.
