ProComp/Speedmaster aluminum heads

Sure that's what the fourms for! LOL
Well first I like the weight loss.
Second I was hoping the heat dissipation would help with not having to have such a high octane level. Get it on pump gas.
And of course I would like another half-second off my quarter mile. And saying that in full understanding that I could possibly do it in other ways..
  1. weight loss - ok, agree
  2. octane level - closed chamber heads are going to struggle to help this. AND, open chamber heads flow better anyways
  3. 1/2 second - You have the power to almost go a 1/2 second faster now, just have to get it to work.
