Most likely, we get cars all the time with mis-fire codes in my dealership that have been caused by use of other plugs.. Chrysler vehicles were made to run on the plugs the vehicle came with..( resistance, heat-range, etc..)Didn't the Hi-output heads have smaller combustion chambers? This may be another problem due to really high compression for what fuel and timing you are using.. I would contact the guys over at KRC performance and ask their opinion..

After working as a gold certified dodge tech for 5 years I have seen repeated misfire failures both with bosch platinum and ngk platinum spark plugs. I would recommend the OEM spark plugs of the proper heat range to see if your misfire DTC go away. Looks like all the cylinders dropped misfire codes?will mustang rims fit a 1988 f150?
You retrieved PO300 (multiple misfire) PO301 (Cyl 1 misfire) 3 and 5 respectively. another thing that comes to mind is that all these misfires are comming from the same side of the engine, the #1 Bank. Be sure the intake gasket didn't slip on that side when installing the manifold... check for vacuum leaks. Seems too much of a coincidence that you have misfires only on one side of the engine...

In my 25 years plus of working on cars and motorcycles I can tell you the 2 crappiest plugs on the planet are Bosh and NGK, throw those peices of you know what in the trash and get some Champion or Autolite platinums. The codes you metioned are misfires on cylinders. That tells you the garbage plugs are misfiring. Period!<ABS> break light in 1996 chevy corsica?
Looks like you have wasted a lot of time and money on a bad problem. Always do the easy and cheap stuff first. Throw away those plugs, go to the dealer if necessary and buy direct replacement plugs for your engine. The HO heads may require a different heat range than the originals, so take that into consideration.More Questions & Answers ...
