Conversation Between LPE 403 and lil john

I'm building a engine similar to you I would like to no how well do you think Mast inline heads would work with a Mast intake and also how hard is that cam with 680 lift on the valve train, I'm looking to drive the car quit a bit. 81 Malibu, 3100lbs. with 4l80 trans 3200 stall. I need help cause I really love those heads, every one recommends me to LS7 or TFS heads with a good intake. Thanks!
