While im at it, let me ask about heads.

[mdiacont322]

Has anyone on here swapped their stock heads to a set of edelbrock etec heads? What was improved as far as power gains or anything else? is it worth it to spend the money or should i look for something else?

I did the gm performance aluminum fastburn heads have no regrets.

 

[mdiacont322]

do you have a vortec? or is it normal tbi? Power gains? Does gmpp make performance heads for the vortec motors?

 

[blueflamed03]

yes they do, not sure if you can gain alot by going to them over good Vortec heads, but you can always bump compression 1 point if you do go aluminum.

I do have a vortec went those heads off a recommendation from a shop here gm says they produce gains of 35-40 hp. I couldn't honestly tell you since I went to a whole new setup so I have had huge gains due to that.

Do you have a part number by chance?
