Which Heads Studs do i have.

[vr4beast]

Whats up i bought this head studs on ebay stating that they were 4g63 studs. One was messed up so i called arp and bought a new stud. I have the stud here but is a little shorter and alot thicker which one is the correct one. Heres a picture of them. Left one is the new one,Right is the used one. I believe the one i bought from ebay is the m11 which is a later model 4g63 and the m12 is the one i just got from arp the one that really goes in my motor.

Are you sure the ones from ebay arent for a 2g 7-bolt? Its still a 4g63 but the stud diameters are different.

6 bolt head studs are 12mm and 7 bolt head studs are 11mm. I was unaware of different lengths however.
