1/2" head stud conversion questions. I am curious at what point it is recommended to upgrade to the 1/2" head stud conversion like I've seen W2W doing? And any ballpark pricing on such a conversion. I know my combo isnt the best but its a starter combo with parts I have laying around. I putting together a F-2 on a 6.0 iron block w/ L92 heads. Didnt know if there would be enough benifit in the additional cost of upgrading to prevent the enevitable time bomb from going off.
Thanks.
Thanks.

Thanks for the input Phil. I knew the studs were the same price as each other just the addition of the conversion itself. I was wondering myself if the deck of the L92's would be questionable before any benifit of the 1/2" studs would play any benefit. Thanks.

Standard size studs can hold very well even around 1000bhp or a little more.
Fitting 1/2" studs to the block, appears to be a very big job, so quite costly.

i did 1/2 studs this past winter becuase with a metric stud i fire slotted the block and head(alot like a mustang, in the center of the bore towards the headers. dont know if that was because my block might have been a little untrue but i did come to find out that the deck of my heads was like a tsunami according to the machinist. a man by the name of Stanley Morton in Tulsa, Ok did the conversion for me i believe he charged 350 for the work and it only took him a week to do it. came out just fine as far as i can see everything sits very nice and the studs were true as far as i could tell.

If the wait isnt too long for l19 do that.
A stock diameter l19 stud is good to 100lb/ft torque same as a 1/2 stud but without the issues of having to have the block machines, head bolt holes enlarged and having to order custom studs.
2 things will help keep the motor together
-make sure the motor is tq plated and bored/honed at the tq spec you plan to use with the new studs
-keep the tune conservative just a little bit of detonation can casue you to lift the heads and blow a gasket.
i have 1 of 3-4 9/16 studded blocks and it's a pain in the ***, custom gaskets, studs, dowels, and a set of heavily modded AFR's that can never be sold again.
