i was going to ferm but went with the new metal gasket set. they were high as hell though. the last set was fel-pro junk. lasted 50k miles. these i bought are the dorman metal look exactly like the ones you are talking about. the intake bolts are a one time use due to they bottom out and then you torque to 11 ft lbs. it's a new GM service update. for the price of bolts may as well not chance it. less than $20.  
  
  
thanks spare but going back with the factory intake as i just replaced the spider with the new MPI upgrade system. just put a new raditator in the truck too ugh. but i did at least use a 3 core solid aluminum tig welded raditator.
