Hello, I am doing a headgasket job on our 05 duramax lly engine.We do a lot of heavy pulling. EFI live towing tune,50-75hp increase. I am planning on using the Victor Rine headgasket, and ARP studs. I have two questions. First- when using stud kit, do you reuse the 5 small allen head bolts that are along the top of the head. Get new ones from Dealer,or do these come with the ARP kit?
Second- When doing a EGR delete does it help to upgrade to a bigger intake pipe available with the delete kits, or is it not necessary? thanks For your time.

I think the little bolts you are referring to are in the kit. Here's a link to what comes in the 230-4201 ARP kit to verify we're talking about the same bolts. The larger intakes aren't needed unless you're looking to make some big power(1000hp +)
On a side note we also offer a LLY Duramax Head Gasket Kit that you can option in the ARP head Stud kit and get everything you need for the job with one purchase.
