Do not touch your heads unless the manifold is ported first, it is pointless. Either way, no, IMHO, the heads are not worth porting unless you are looking to set some kind of an N/A record and need every single last horsepower available... and that would be a couple hundred over 700. The heads flow good enough in stock form, better than pretty much any Gen-1, 2, or 3 ported casting and about the same as Strikers. Even the Big Power TT cars would be more benefiting from leaving them alone and keeping the extra material in the heads for strength, as they flow more than adequate as is. Go with:-ECU-Filter-Headers & Exhaust-Manifold Porting-Spark Plugs RE7PYP6EASY over 600 RW on most cars, which would be a hair over 700 crank.
Thank you sir. That's kinda what I figured after reading the other thread. I have smooth tubes with stock airbox and K&N filter, plus a Corsa track exhaust. What brand of Spark plus are those #RE7PYP6?
I noticed you mentioned "filter"I tried a KN filter. It kept triggering a cel and put car in limp mode. I checked around and it seems a lot of other people were having the same problem. Apparently the oil in the filter would mess with the MAP sensor. I put the OE filter back on and CEL went away.Have you heard of this?BTW, SHOOTER t1.... The Mopar controller will really "wake up" your car. Especially in the midrange. Which is obviously ideal for a track car
