My car started pushing coolant the other day so I pulled the head today to see whats up and as suspected, BHG. I was trying to figure out why it blew because my head has been checked and its flat and it never had head gasket problems before. I noticed right where it was leaking there is a coolant port that Felpro blocked off. I did some research and found that people have noticed it before but I could only find references to 1g cars and although there is a port on the block for coolant to flow into the head 1g heads don't have the port opened up. Well I happen to have a 2g head on my car and it just so happens 2g heads have that port on the head also. I couldn't find a refence to this problem on 2g cars or heads so I figured I'd post some pics because I believe that this oversight on Felpro's part contributed to my BHG.
This is my 6 bolt block compared to my Felpro HG
This is my 2g head, also has that coolant port that's not present on the HG
This is a 1g head, notice the missing coolant port
This is the HG that was leaking, it even looks like coolant was trying to get through that hole
