Mike do you have the Chevy 2.8 studs, if so I would take them off your hands? Let me know, I think Robert and I are going to work on his 95 this weekend, if you are around I would pick them up.

well I threw a rod in my car..but the hg's/arp studs heald up...lol


as for the machining...I had the heads milled and i cleaned the block real well...other than that...i didnt do anything out of the normal for the MLS hgs(I used felpro) but again I have a 97, so a 93 or so from your profile might not be the same.

I have an 89 t-bird supercoupe with some engine modifications. I have an 70mm bbk throttle body, proted heads and intake manifold, kook shorty headers with down pipes, 2 1/2 exhaust, supercharger pulley, spec 6 puck racing clutch and 11.5lb flywheel, 3:55 rear end gears, adjustable fuel pressure regulator, 38lb injectors, 75mm calibrated mass air flow sensor ,and 255lph fuel pump. And before i had put all these parts on i blew the stock head gaskets, both of them. So in tearing the heads off, i thought i would had some performance parts, so i figured it also wouldn't hurt to through some 99 mustang fel-pro 3 layer steel head gaskets on. And with in less than 200 miles i blew them and i mean between the cylinders i am missing about a quater of an inch. And on this second tear down i noticed that the head bolts on the outer edge of the head, the bolts were alittle easier to break free than the ones under the valve cover. And the guy i bought the car from had told me that the ecu had been chipped, havent looked yet to see if it is, but i was told that the early chips made for the SC messed with timing a lot. So i was thinking that under boast when timing is already advanced could this chip be advancing timing even more causing extreme cylinder pressures, which happens under a lot of advanced which would cause the head bolts to strech and let me keep blowing head gaskets? And what would be a could head gasket to run? And is there a good chip out there to maybe allow me to tune the engine alittle bit? And so i just ordered some ARP head studs to help the bolt streching a bit. PLEASE HELP

Sounds like the block surface wasnt as smooth as it should be for the MLS to seal. they have to be usually depending on brand 10-35RA (roughness average) if not then the MLS hg's wont seal. Thats why I asked earlier about machining. I had to do this on my supra. I started off as just a MLS hg prep then turn into a major build. I got everything back from the machine shop and the block wasnt as smooth as I liked it so Im lapping it now along with the head. Using a lapping tool and compound. My tbird just recently blew the hg's and I was just going to use the stock composite ones with new head bolts and torque them down a little more then what the manual says.
