What kinda head work needs to be done to handle 65psi? Will just studs do it or do I need more?

I've heard of just going and re-tightening your stock studs and you can handle a bit more, does anyone know about how much the head can handle with just re-tightening stock studs?

 

o-rings on the head will handle 65psi with a stock gasket and studs but thats about the limit im having the block and head o-ringed.

 

so o-ring the head and stock studs? or aftermarket studs?

 

Stock, they are "bolts" not studs.

 

whats a ball park figure on how much it will cost to get it o-ringed

 

I am more concerned on who will do it. No one in nh does that stuff.

 

i got my head o-ringed for $250. i have o-ringed and ported/polished head and am running 12mm arp studs with a .020 over marine gasket

 

how many PSI should one expect to have when running around 400rwhp

 

dont mater about psi it depends on the size of the turbo. you can have the stock turbo at 30-35psi making 400hp or you can have a aftermarket big turbo making 20-25psi paking 400hp it all depends on what you got for modifications

 

if im going to o ring it and have studs should i just be putting back on a stock thickness gasket or something a little thicker? is there a benefit for using a thicker gasket or different gasket then stock?
