Alloy Heads

I have a very similar combo on a 366CID with 10.7cr.By most peoples reckoning around here thats pretty hot.(goes 93 in the 1/8) Im very pleased.
With your extra cubes it will be an especially HOT streeter.
BTW if they really come in at 58cc chambers, they will make a lot of cr with flat-tops and zero deck;so pick your pistons carefully.
