    why are you changing the head gaskets when there are no heads on your list?

    Also why such a small cam?

    Your not going to get away with a 3.4" to a 2.8" by just adding a cam and injectors...MAYBE a 3.0". It's a GenV car guy...a 2.8" on a GenIII is a XP/IC/Injector/Header/Tuned car...like I said...your looking at a 3.0"-3.2" area.

    I painted the chrome grills black, went around the edges in red, and finished with clear coat. I'm going for cometic head gaskets, because I trust them and I don't mind paying the extra $. I'm staying with stock heads, and running an XP because this is a daily driven car...

    Stock heads...stock head gaskets...hell even I am running stock Felpro's with my hogged out heads.

    I've seen and heard of a few vacuum leak issues with the MLS gaskets not sealing properly. Just get the Felpros...if you want to bump compression a tad...which is what your doing by getting a thinner gasket...have the heads or block milled a smidge.

    Since your head gasket is leaking i would also go for the fel pro's.

    I'd like to know how and where the head gasket is leaking and what you've done to confirm your suspicions.

    Simply because head gaskets dont seem to be common at all on 3800's.
