472/500 cid Grade 9 Head Bolt Kit.
Unless we're building a high performance (500hp or above) motor at MTS, when given the choice of bolts or studs, we always use head bolts.
Our 20+ years of Caddy experience has taught us this valuable lesson. There is nothing more frustrating, or an easier way to hurt yourself, than trying to lift a 75 lb head up over a set of head studs. Backs, fingers, (toes if you drop it) are all at risk in attempting to lift a head up onto the already in place studs. Not to mention, the possibility of damaging the heads or valves by scraping them on the stud posts.
Plain and simple, it's just easier to set a head on the motor, and then insert the bolts.
On 95% of 472/500 applications, (other than the high performance racing engines mentioned above,) MTS' head bolts kits work just as well, if not better than studs.
Each MTS bolt kit comes complete with all 20 pieces needed to mount both sets of heads.
