6 bolt/7 bolt deference

[4g63turbo84]

I'm going to be buying a motor gasket kit and found out that there is a kit for the 7 bolt and a kit for the 6 bolt and I'm trying to find out the deference between the two...

and this is my set up i got a 6 bolt block with a 7 bolt head

Doesn't matter I have a 6 bolt block and 7 bolt head. Head gaskets are the same. I just have a 6 bolt head gasket. I have ARP studs I just had to drill out the holes a little for the 6 bolt headtsuds.

Get the 6 bolt kit. Some of the other gaskets are different between the 2. Such as thermostat housing, front cover, ect...

You only have to drill out the 2g heads....

Correction, you have to drill out 7 bolt heads. All 7 bolt heads use the 11mm bolt holes(1g 7bolt and 2g 7bolt).

6 bolt heads have the 12mm bolt holes.
