hey guys I have what I think is a 99 teksid block and I'm told that the factory main bolts are one use only variants so I need to replace them right? (please correct me if I'm wrong). The issue is i'm not sure exactly what ARP bolt kit I need to get. one is for windage tray and the other isn't but my block has 8 studs for what i thought was the windage tray and the ARP kit only shows 4 studs available.

the engine is at the machine shop so I need to get this figured out today. what should I do?

here's my block:

First off that doesnt look like a teksid based of the main caps and the casting structure. I think you have a WAP block or an 05+ piece. Do you have a picture of the valley area or a part number?

Look at some of the modular suppliers and see who offers the stud count you need. If you're running a windage tray you need 8. If you choose not to you only need 1.

looks like i was wrong about the teksid thing, not a problem except I want to make sure I got the right bolts. this is so damned confusing.

So yesterday I ordered these 2 arp kits that are supposed for be for any aluminum:

ARP 2565701 4-Bolt Main Stud for 4.6L 4 Valve with Windage Tray Modular Ford
ARP 156-5001 Main Cap Side Bolt Kit for Ford M8 Modular Block

If you look at the pic on most sites you see 4 studs for the windage tray but on the following link you see the 8 studs for the windage tray for the same part number. I don't know what to believe.
