tool steel studs, maybe?

 

I don't think a tool steel stud could be properly torqued.. I can't see tool steel stretching any.. And the stud stretch is what keeps the tension..

 

I've done it on dart heads.You will prob have to pull the rocker stands to retorqe the heads.On yates heads you have to no matter what.

Id call who made the heads and ask them if they are thick enough to drill out.

 

imo...having only ten studs is the main problem.

 

i have and it sucks finding a machine shop tha has a tq plate for 9/16 studs. i had to end up having one made and the last shop who died my motor kept it and are now out of business.

 

Never heard of anyone doing this before, I have BF202s on Dart Iron block, 40psi of boost, no head gasket issues with 1/2" studs.

 

Whats the bor on the r302 ? Is the carbon tracking on the head or the deck ?

 

What would be the difference if it were on the head as opposed the block?

 

There were a couple guys in Oklahoma doing it a few years ago. Broke a head.

 

I second the thought on tool steel head studs....

 

anyone have any info on someone who does the extra studs per cylinder, im having same issue ...lifting the head thinking more studs will fix the problem.
thought of going to 9/16 stud but worried about block cracking on the eds where there isnt a lot of meat around the stud.
im using dart compacted block has same issue on r351 block

 

yes roush great guys to deal with also. pm ben mens on here he will hook u up

 

I started out the same route you did scott..The coppers were what i was told to use & that was a big mistake...You switch to the cometics & i promise you won't regret it...I have 2 or 3 friends running turbo's had the same problem also & cometics fixed their problems.....

 

I have pondered on the same issue , Scott .. I still havent found a real good reason for the 9/16 stud.. I have seen alot of guys running them and also have seen their gaskets and the carbon tracking between the cylinders is still there... IMPO I would highly recommend to switch to Cometics .. I know some will tell you they arent sold on them yet .. But the MLS is a smarter choice on a SBF esp. when you have aluminum components..

The head lift is very common that is why the copper sucks in a sbf .. I switched to Cometics and every , And I mean every problem I had with the copper gaskets went away when I put the Cometics on it .... Tune is more critical also with the MLS ... The coppers are a krutch for a bad tune and is the weak link..

 

I have 9/16 in mine using high ports. I torque 145 molly or 175 with oil. You can hone the inside of stock dowel pin to clear the 9/16 stud. My heads were notched for the bigger nut/washer but there is plenty of room between the valvetrain. ARP sells these studs individually so close to SBF lengths they work. The Ford Big block studs are too long.

 

Iagree with sscobra .Cant beat Cometics,as long as you have the correct finish on the deck and cylinder heads.

 

I'm still using cometics but i don't know why some claim better than coppers. You have to use a 51 wire and groove both the head and block for copper to work right. Cometics have there limit especially on big blocks. I like the flat out copper it has a viton coating all over. True with coppers you have no fuseable link. Whats good about the cometic they are like a rubberband if the head moves but your still losing seal.

 

torque a headstud using spacers to your spec and measure how much stretch it has should be around .001 per inch if not send me a pm

 

my engine builder made me use the copper head gaskets when i didn't want to and i had nothing but problems even tryed the titan and it was a little better but the problem was still there i pull the motor had him redo the deck and heads straight with no grooves
and went with the fel pro mls, solved my problem never had an issue not i time i've had to worry about water in my cylinder when before it was all the freaking time, never used cometics but know people that can't get them to stop seaping water out the corners.
fel pro mls never heard anybody with that issue

 

That's because Fel Pro had a thicker sticky coating. I thought fel pro quit making that gasket. Problem with Fel pro you could not custom order thickness. The flat out copper gaskets have the viton coating. Cometics need a real slick surface get some tubes of ford/IH diesel gray slicone and some copper coat Fill the block about an inch from top(hard blok) don't pressurize cooling system and get a big puke tank:smt082

 

Get ARP to make a set of 1/2 studs using their Custom Age 625 plus material. It has a tensile strength of 260,000psi versus the 8740 that is between 180 and 210,000.
