Engine 88 GT head gasket question

[Comp Cam]

So I'm thinking about going turbo this year. I was wondering if I run a 9333 feel pro head gasket will I have to my head's machined? Or can it just be dropped in as is?

With boost in these 5.0 engines the head gasket installation needs to be perfect or near perfect. With only 4 bolts around each cylinder, theses engines are already known for head gasket problems. Add the dramatically increased cylinder pressures of a boosted application and head gasket problems will show up unless you take all measures to ensure things are as good as they can be. Both heads and block deck need to be properly checked for flatness. Anything out of spec even .001 and you're asking for trouble.

I had 9333's with milled heads and ARP head studs. Head gaskets still wouldn't hold. I didn't solve my problem until I had the block decked and went with Cometic gaskets. That was my experience anyway. Others may have different

Well man, I'm leaning towards the cometic gasket because I don't want that problem. Any idea on how much it would cost to have my head's resurfaced for comectic gasket?

I think I paid $60 per head for milling. It can vary widely depending on shop and location. When the heads are off, get the deck fully clean and check it with a straight edge and feeler gauge.

In the above video, obviously the block is out of the car. But you can check it with the block still in the car.
