Wow. I took a dumb question and made it really dumb didn't I? My questionwas directed at the heads of my 1997 318. 5.2 motor out of my 1997 Dodge RamB2500 Van. I had #2 spark plug frozen in the head, ended up having to pull thehead, actually pulled them both as she has 115,000 miles on her, and took themto get looked at only to find they were both cracked between the valves. Thishas lead to some pretty bad stories about 318 heads. But, $480.00 later I gotme some reconditioned heads and ready to bolt the old gal back together. Thanksfor the assist and I apologize for being a little shy the information foranyone to help.
