After going thur all the records on my used coach I changed the plugs(V10) and sooo glad I did cause the short thread plugs were not very tight. However no damage done and all is good with the heads and double platinum nickel should last many miles. Btw never use a black plug on alum. heads which was what I found. I torqued to 20 ft. pounds. Now I can sleep after reading horror stories about plugs blowing out.
