203-5402 is going to be the main studs for the connecting rods i believe.

203-4202 is going to be the head studs

main studs are for the main caps that hold the crank in, not for the rods, but yes the part numbers do match to that.

Okay thank you very much cause they were not specific

Btw, there are in fact two versions of head studs for the 7mgte- regular, and undercut.
Not sure if one is better than the other, though i've used both.

The undercuts are going to be better, they are designed to ease assembly and threading of the nuts along with uniform stretching to prolong head gasket life under higher cylinder pressures.

Appreciate the info.

You have used the undercut studs before? And you are positive those are way better than the regular studs? Because I'm buying them this Friday so I need to make sure I get the right ones

Not necessarily on a 7m but ive built a couple drag motors and always go with undercut studs from arp for the heads. Rod bolts I use carr (expensive little bastards) but they have a tensile strength of 1,000,000psi. Anywho definitely go with the undercuts, you wont regret it.

I agree with the undercut information...but 1000 kpsi, you might be talking about different units :biglaugh:

That's what I was told by the rep lol I ordered them through my old college.
