I am new to the LSX so here goes. Just got my 427 LSX and I am looking to make 900+ HP then a little spray later. Well my question is whats the best head to acheive these HP goals? How goo are the LS7X heads? Will they mount and make the power?

Can't really say without knowing more about the combo you're using. Going FI or N/A? How big is the motor?, etc

Its a 427 LSX short block from JEGS. It will be N/A, carb with nitrous later down the line. It has dome pistons and havent choosen a cam yet. I just wanted to know if they would fit since they flow really good, if not what are some heads that flow 390 or better for my short block.
