I would go with the ford racing graphite gaskets with headstuds. I used there supercharged gasket kit from summit with my 5.0(it comes with stretch bolts).

shouldnt use studs, you should use arp head bolts, if you want to cure head gasket failures look at the SCE Titan ICS gaskets.

Just use some Fel Pro's and some STUDS and get a better tune.
CDT get your facts straight, read ARP's 2005 catalog pg. 36 that compares bolts to studs. It's called TORSIONAL stress.
STUDS:
More accurate torque reading More clamping force vs. bolts Reusable more times then bolts (especially stock ones that may stretch)

only reason I can think of for not wanting to use studs is its damn near impossible to install the drivers side head with studs with the engine in the car, the brake booster/mc are in the way of putting the head over the studs.

I have had great luck with the felpro wire loc gaskets. I would stay away from anything ford. The felpro's have a pre flattened stainless wire for boost applications. I have had mine for 8 years. Also running 8 psi. S Trim. Also use ARP Head bolts.

maybe you should ask why someone said what they did. It is all about stress, studs will stress a block differantly than a bolt will. You can ask pretty much any engine builder and they will not recommend switching fastner type on a engine after it has been put together. If he was building an engine I would say by all means use studs, unless it prevents head removal in the car and you have a choice.

nothing wrong with switching to studs. Unless you had your block honed with a tourqe plate with a certain fastener I don't see were it would Make any difference. I did it to my 331 no problems here. BTW I did swap to cometic gaskets but for just stock compresion and stock blower pulley I thought it would be over kill. BTW I don't need to ask any engine builder I build them myself [ December 23, 2005, 02:53 PM: Message edited by: 2stangs69-91 ]

I understand that studs would distort the cylindrical hone but I have seen many people do the transfer from bolts to studs and have no problems.
Other than distorting the cylinders to the point where rings could lose some of their seal I don't see any other disadvantages. Ring seal sounds like a big problem yes, but I would like to see the % leak to see if it was substantial.

theres just so much you can get away with when building an engine. not that i take any chances or anything . 99% of the time you probably wouldn't have any problems switching to studs, unless, like 2stangs said your block is machined the way its going to be ran. as in torque plated with studs, align honed with the girdle or no girdle in place, therefore you would want to use the same type fastener and torque the machinist used. and yes studs are stronger but mainly because their only enduring 'stretch' as a bolt is enduring a 'stretch' AND 'twist.' definately look into the SCE TITAN copper head gaskets, not only are they copper, they also have a raised seal around all water areas. these we'll never leak, we've had great success with these gaskets so far.

Fel pro #1011 and ARP Studs why take chances? Get quality proven parts that unlikely to fail!
