Well, I got my very own BHG, so I am in the process of replacing that, and fixing various other problems while I'm in the engine. Ill be posting my progress (with pictures) and my questions here.
Here's the story: i got my '87 turbo supra a couple months ago, and the PO (who i have since found out was retarded) said that it had a GReddy 3mm metal HG on it. Now, I knew that GReddy didn't make a 3mm gasket, but I figured he had the number mixed up or something, and didn't think much of it.
Since then, ive had random overheating problems more and more fequently, and was losing just a little coolant, but no milkshake oil or anything else. I almost overheated it a couple times, but I never once let it get into the red, just about 3/4 of the way up or so, maybe a little closer. the other day i went out to check all the fluids like always, and i was almost 1/2 a gallon low on coolant, and i had chocolate milk colored oil. crap.
So i know i have a BHG, and am in the process of taking my head off to replace it. I plan on using a OEM composite gasket as I dont have the money to resurface the head and block, and wont be doing any modding until next year, when i plan to build the motor.
---Question: Do i absolutely have to take my head to a machine shop and have them check for flatness and plane it flat? Or will i be okay using a stock gasket and arp bolts torqued to 85ft/lbs, and just putting the head back on after i give it a good cleaning?
Ill post some pics later when i get them off my camera.
