my block is decked .060, and heads are decked .060. i didnt know the chamber size so i did a quick google search and they had claimed 113. but yeah i jus checked mortec and i would trust they're stats. and as being too big, i mean do you think they would flow too much and not be able to pick up at low end. I dont have my sheet by me of my flow. but i do need to cut the intake to 2.19 to bring the % to 75%

ill find it in a bit and post the flow..
im running a forged crank, rods, and KB pistons
