Cast vs. Aluminum heads and bang for buck..
- Push rods needed for the LA, not if I use them on the magnum. You have aftermarket pushrods for your LA ?? So call it even.
- I'm not sure you'll get this, but I think for my motor, the mag heads I have will give a better ET than your Pro Comps on my motor. IF ET is what we want, then I will stick with my 600 dollar heads rather than your 900 dollar Procomps.
I'm going to go ahead and dispute your flow numbers as well. I'm going to say these untouched Speedmaster heads would flow better...
