had a bad head on the left hand side of my 6.0 engine I bought new heads and put them on now it sounds like my engines hammerin like nobody's business and the bottom end was solid and had good compression before I did it is there any idea what's going on

I'm concerned about the engine timing as the pistons meet the top of the stroke. You really need to get some professional eyes on this, but it can also be too late. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
