ProComp/Speedmaster aluminum heads

We have at least 3 threads going on this. Go back to the other thread and I laid it out there. Hughes is wrong. Read what I posted over there.

BTW, I think it was the road kill dude and the long haired Chrysler guy who's name...Dulcich...did a test with the dude form Westech...I'm horrible with names..I can see the faces but can't think of the names...did a test on aluminum verse CI and they found nothing.

Just like I have been doing since 1980.
LOL... I replied to your post in the other thread. your coolant remarks I hadn't thought about, which made my points "less factor" although not "non-factor". thanks.
