bolt them on bro! the only problem i know of is bolt holes in the center of the intake need to be elongated a bit since the holes on the alum heads are the same as 86 and older heads whereas your intake is for the 87 and newer style not a big deal..... perfect time for a Stealthram

They are the same heads the L98 Corvettes used in the late '80s/90s.
