Can anyone tell me the 4 digit head # that is used on the 3800 supercharged engine. I have 5 sets of heads and one note on one said for the 3800 SC engine. Thanks.

Re: Super charged head #'s
From the article "Rebuilding the 3.8L Buick":
1996-’07 VIN 1/4 (Supercharged)
The heads for the Series II/III supercharged motors are similar to the ones used on the regular engines, but they have three holes right above the intake ports for the injectors. Look for a 4781 casting.Last edited by pace2006; 07-27-2010, 10:08 AM.'99 Camaro
