Okay guys getting tired looking for the part number.. 2005 Lq4 stock bore with boost down the road.. MLS gaskets for boost correct? Anyone have a part number? Want to make sure I order the right ones.. Thank you!

 

12589227

 

12622033 if you want to go with the more "boost friendly" LS9 gaskets.

 

^^^ this too. Guys have made 9xx HP on them with no issue. I am running stock 6.0 MLS ones on about 12psi, with out any issues though..

 

Thanks that's exactly what I needed to know! Not sure what the ceiling will be as far as power so the ls9's look good just for the added insurance..

 

i went with ls9 seven layer gaskets,u should too buddy imo
