ProComp/Speedmaster aluminum heads

Then I can make it simple with these questions. One word answers.
  1. Does aluminum dissipate heat faster than cast iron?
  2. Does air being contained (cylinder, balloon, tire) lose pressure in cooler temp?
  3. Does less cylinder pressure create more or less horsepower?
  4. So IF aluminum creates less cylinder pressure, does it allow more compression to be run to make up for the loss of cylinder pressure?
Again, how many different engines somebody has built or what credentials they have, it's really this simple to me unless somebody can explain it with better logic. I'm not saying I'm right, but until my simple logic is debunked with better logic, I have to stand by what I think... for now. I'm always open to learning.


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.
