7 bolt head oil passages

Am I losing my mind or does this head have 5 oil ports on the passenger side of the head?

You’re asking like this is abnormal. All of them except the top right one circled are plugging drilled ports purely to create galleries for the oil to flow through the head.

The top right one was used as the turbo oil feed for 1Gs and was plugged on 2Gs.

As it is a 2G head, it looks perfectly normal.

The only thing that looks different to me is the upper right one (Oil feed on 1g Turbo) is blocked by a set screw and I've always seen them blocked off by a bolt and copper gasket. Nothing wrong with the head though.

Oh nice. I've never really looked at it and wondered why they were all capped.

Well I'm running a ffofh (mighty max reproduction I think) and it has one oil port. I installed the factory pressure sender there but that's all. So I'm planning to run the turbo feed (Bullseye Borg Warner S259) from the top right circle of the head where it's currently capped off but I also need a place to stick the oil switch sender for the dummy light, any suggestions?

It's worth noting that it's a 7 bolt with balance shafts removed and the prior build resulted in oil pressure being super high. I imagine this will be the same way. I don't believe it's a ball bearing turbo so the pressure should be ok. Also, there's 2 ports in that upper right spot. One on the passenger side (pictured) and one an inch to the right on the front of the head in line with each other. I'm reluctant to use both even if one is just for a switch. Suggestions?

I could tee off of the filter housing but I don't know how a dead ended tee would effect readings

Leave the plug on the exhaust side of the head alone. No reason to tamper with it.

Consider remote mounting your sensors for the oil filter housing to keep extra weight hanging off of it - which could ultimately cause the housing to crack: 1G Forward Facing Oil Filter Housing
