hey guys, just wondering if i could get some opinions. recently i blew 2 spark plugs through the head (both on passenger side). i helicoiled both of them and tried tomake surethe torque was right on all plugs. should i replace that head before i install the supercharger, replace both heads, or just wait until after installation if and whenthe head goes bad?
i really didnt plan on heads or cams cause i know theres alot of money in that. opinions or past experiences would be greatly appreciated. thanks

i would replace the heads and cams before you s/c. dont feel bad i blew the same plug twice already within the last week...
