I'm just (IMG:style_emoticons/default/icon_bump.gif) ing this thread to see if there are any updates this year about these AA heads. I wonder if McMark or HAM Inc have any recent thoughts about the current quality of these?
Thank you. |

I'm just (IMG:style_emoticons/default/icon_bump.gif) ing this thread to see if there are any updates this year about these AA heads. I wonder if McMark or HAM Inc have any recent thoughts about the current quality of these? Thank you. I've been very impressed with the consistency of the castings. So far they have all machined very nicely and the dimensional consistency of the machine work has been spot on, ie, valve guide bore sizing and spacing, chamber heights and volumes, I could go on. I have now done a fair amount of flow testing with different valve sizes and port mods and found some specific details that these castings respond very well to. Not willing to share those specifics here, but our customers will benefit from this knowledge. Like all other T4 heads the AAP's are capable of making impressive power with the right mods. Still too soon for me to speak of long term service life, but we have gotten nothing but positive feedback regarding valve adjustment consistency on the heads in service so far. To date, every pair we've prepped has received ceramic coating to the chambers and exhaust ports. This will extend the life of any T4 head. World member Shane Sparks got a seriously bad-ass pair of these heads for his ChumpCar. Shane has agreed to share his experience. Endurance racing will be an excellent test of these and any heads. Overall I feel pretty good about these heads, so far, and think they are a much better choice than 40+ years old O.E. castings. Time will tell. |
