- ARP Connecting Rod Bolts
- ARP Main Stud Kit
- ARP Head Stud Kit

No head porting?

Oh yeah, I knew I forgot something.

I want to send off my extra set of 5.3 heads to Absolute Speed and have them do a stage 1.5-2 port/polish, vavle job, etc.

Forget the rockers.

I think the ARP main studs are overkill, plus you are supposed to get the main journals realigned if you use these, if I remember right.

The ARP head studs might be overkill too, but heck I got those and got my heads o-ringed too, so don't listen to me on that one.

Why the thicker head gasket? That will lower compression by a bit...

Thanks for the info guys! Keep'um coming!

I was wanting the thicker head gaskets, so I would lower the compression just a tad. I figure it wouldn't hurt considering the 5.3 heads would bump it up to ~11.xx anyways.

So, just reuse the stock head studs and roller rockers, right?

Your thoughts on the gasket make sense considering the 5.3 heads.

You'll have to get new head bolts, can't reuse those. If you plan on pulling the heads more than just the one time, the studs are good because you don't have to keep buying bolts, and you don't have to keep cleaning the bolt holes...

I just plan on pulling the heads and when the new ones come in, putting those on.

Does anybody know all the torque specs for the LS1? Like the roller rocker arm studs, valve cover studs, all the head bolts, etc.?

I would not buy the bearings from the dealer unless you want to pay a FORTUNE! Get the bearings from Thunder Racing or another sponsor.

There are better bearings out there and no need for the Heavy duty Comp Cams timing chain. You can just use a new stock piece. FelPro makes a new set of head bolts that are cheaper than studs. Either reuse the stock rockers or get a set of Harland Sharp roller rocker much cheaper and then you don`t need the valve cover spacers either. Main studs not necessary at your level as said they do require a line bore after installing them. Hope this helps let me know if you have some other questions. I can get you all the parts you have listed just let me know.

I have some slightly used stock length MTI Hardened Pushrods I could sell you. They were used for about 1500 miles with my MTI B1 Cam. I've since changed cam and heads and needed shorter pushrods. $40 and they are yours.

PS. I'm going to post this in the For Sale section too.

Compression Ratio with 5.3 Heads and Fel pro's should be about 10:9.
I'd go with a little bigger cam if I were you. FMS is a good start. Those cams seem to produce tq. under the curve real well.
