Small block W anything is really not in my future. I do however have a brand new set of G3 heads here all ported, but still looking for a 6.1 block. I might just bite the bullet and get the aluminum one if my tax return is any good.
The heads I have are the MW port size already. My thoughts are between the EZ295-325 & -1's at the moment. Mine flowed 327 at .600 and fell off after that. I run a .680 lift cam.
