Good post up there @SkinnyG

OP I bet after you start running the 416s you'll love em so much that you won't find a good reason to change em.

Once again thank you all for your help! Time to get the heads cleaned up and start doing some work. Any other suggestions or ideas for the 416's is much appreciated

These 416 heads have a 1.70 intake valve. Kinda confused thought they came with 1.84. Not sure how much that's going to hinder their performance

I think they came with both.

Well plans changed unfortunately! The number six piston decided to let go on me. I rebuilt another 350 I had in the garage, new crank,rods, pistons everything. Ended up going with an edelbrock performer cam and switching back to the swirl port heads.
