I am just wondering what you can usually run for boost numbers before you start having hg issues?

Its a benson sleeved ls block 84mm. With b16a head, cometic hg, and arp studs.

When is it recommended to use o-rings, and what do you run for a gasket with them?

 

well im running same setup with gsr head at 35psi... no issue

 

dont worry. you'll be fine just with the headgasket you have.

 

Ok... cool, Does anyone re-torque the head studs? I know this has been recommended but does anyone actually do it?

How much power are you making @35psi?

 

i made 812hp and yes i did re torque to 90lbs

 

90 ft lbs.

 

Holy ****... well i guess i better get on that... Mine are only like 75 or 80.

 

i have a question to, i have b18c benson block and what do you think about coper head gasket, like SCE (i have one already on the shelf)? i'm planning 650hp

 

MLS has been the norm for years, don't use a copper gasket. If it works, stick with it.

IMO 90ftlbs is a bit high. This has been covered here a number of times.

 

why don't use it? i don't know that works or no becouse right now i'm building this motor

 

What do you guys like better o-ringed block or step deck?

 

Why not both?
If you're looking for high boost, then I would suggest both.
