Ok car guys what works good at removing Buildup in Aluminum Heads in the Intake & Ex ports where my Valve seals where bad ....

I tried WD-40 and carb Cleaner any help would be good just don't want to use anything on it that will cause Damage to the heads.
 
I have used lacquer thinner on aluminum intakes and it works pretty good using a brass wire brush. If they are off the car you could always have them glass beaded.

Good luck

I had someone else say Glass beaded or Soda Blasting
 
Mr Muscle oven cleaner for aluminum. But if the heads are on the car, it will damage any near by paint.
 
Try some brake fluid. It removes paint, so...
 
From one of the world's top makers of aluminum heads - Briggs & Stratton...

1. ... scrape carbon gently from the cylinder head, using a wooden or plastic scraper. Take care not to dig the scraper into the aluminum. On stubborn deposits, use a putty knife, wire brush or steel wool (images A, B, and C), taking care not to bear down on the metal surfaces.


2. Clean away the remaining carbon with solvent, using fine steel wool to smooth rough spots. You can also soak metal parts for up to 15 minutes to remove stubborn deposits. Scrape again, if necessary, to loosen stubborn grit. Then, clean the area thoroughly with the solvent and set the head aside.
