Does GM make LO3 replacement Heads?
Hey guys, I think I have bad Valve seals and or Guides, I was thinking of just getting replacement heads. Are there any heads out there that would help in performance that are not too expensive? and does Gm make the LO3 heads anymore. Thanks alot, please help with my problem

What ever you do, do not get LO3 HEADS, they are not very good I heard that they are one of the worse heads that gm has ever produced! Any ways I think that world makes some good a good pair of heads for 305 that are not too expensive depending on how much you want to spend.

Get some S\R torquer 305 heads. They aren't too expensive, and flow well. It has the same chamber volume so you will have the same compression.

they don't have EGR passages so you need to see if you can get away with not having them.
