Weight reduction is not a huge factor, I am assuming the availability of new alum heads is better than cast. With an overdrive trans, it will not be pulling high revs, so I want the power band down low. Has to run on 87 octane, so no high compression, hate detonation ( I have that issue with a 10.5 CR 350)
So with low end torque as the goal, what heads would you go with? They cannot be Vortec as I have a vintage alum square bore intake for the EFI. Plus they have to have steam holes.
