i laid on the engine bay and was able to ge the last plug without moving/removing anything. i guess i got lucky.

 

.057 seems a little much to me.. if your running a h/c package, I would run them at about .045"

 

ive heard of alot of issues w. MSD's if ur going aftermarket, i vote for Taylor 8mm or 10.4's plus fire sleeves to prevent arcing

 

Ok, I pulled the iridiums out, checked them, the gap is maybe 1-3 difference than the 55's it had. seated and reseated the iridiums and the plugwires. no matter what I did, I couldn't get my car to run right with the iridiums, finally I put the original plugs back in it and it runs perfect again. WTF?

 

Dunno what the deal is with that... but after hearing this, I'd advise staying away from the iridiums.. sound slike they are more trouble,and more expensive then they are worth.
