What heads do you have that are causing all of these unnamed problems?

i have the stock l98 cast iron heads. the valve guides are bad and are in need of a rebuild so i was wondering if while there off i should go another route.

Re: full bolt ons head options
I would definitely go with aluminum heads of some kind. You might consider Corvette L98 aluminum heads, Or go the Summit Racing for their alu heads or Patriot Perforamnce.
Also, new valve springs are in order, so purchase a pair of heads that are assembled.
Use the 1010 Felpro head gaskets for any of the above aluminum heads.

If you aren't changing the cam, just have the stock iron heads worked over.
