Hi Guys,
I’ve been looking at the cylinder heads from Competition Components, and they seem very appealing.
CNC Ported Competition Components Small Block Mopar Heads
But, before I make any decisions, I’d really like to hear from anyone who is currently running these heads—or has run them in the past.
How is the performance, build quality, parts quality etc.? Any real‑world feedback would be extremely helpful.
For some background:
The car is a street/strip.
My previous setup was with ported J-heads with 2,02 / 1,6 valves, running a hydraulic roller cam (Howards 712105‑10), about 9.5:1 compression, and a fairly streetable combo.
I’ve been racing it on and off, including some 1/8‑mile runs (7.36 @ 150 km/h).
Now I’m planning an upgraded top‑end. I’m looking for stronger midrange and better top‑end airflow without going overboard.
That’s why these Competition Components CNC heads caught my attention—especially the 2.08” version and the fully CNC’d chambers and runners.
But since they aren’t very common in the Mopar LA world, I want to know if anyone here has real experience with them.
Do they live up to the flow numbers? Any issues with valve geometry, rocker clearance, or cooling?
Any input, good or bad, would be greatly appreciated.
Best regards Daniel
