I had those heads (stage VI P5249579 Mopar performance heads) on my 528..

They are not good, or maybe closer to crap ootb..

Don't waste your money going that way. While they will make good power when finished, you'll have far more $$$ in them than if you went Victor MW.. from experience. I had $5000.00 in those heads..

Car went 9.20's @ 145 in good air @ #2900 w/ a glide and a spragless 9".. But I could have had a real nice set of B1's for that $$$..
