im gonna start very soon on this swap since the snow is gone and i got a car to drive while the ef is in under the knife. i can either go z6 or y8, got a b2 block that im building on so if anything its getting bearings and seals and perhaps some new rings. i am just not sure on which head to go with and i got about 500 that i can start with now.

looking for opinions/suggestions on which head and why...i dont want to do a b series, i have already made that decision. its not an option....

so fellow ef guys give it to me and let me know what yall think!

thanks in advance
