I have a dilemma with a parts choice. I want a set of heads and I am leaning towards the Livernois stage 2. The problem that I have is I am still running MAC headers with a catted Y. I can either get a set of really nice longtubes or these heads, they are about the same price. I'm not sure what the most cost effective mod would be. I havent seen any dyno graphs proving what headers are better than others, but i would like to see people that run a H/C/I setup with MACS. The car dynoed 369 RWHP unlocked, Mods are in sig. I tried a search but found nothing.

 

go for heads man the headers will still work fine for you ,just get it when have extra mony to swap headers the swap will not give you more 10 hp .but the heads will put additional 30-35 hp . go stouter bro !

 

save up and get both at the same time. it would be allot easier to put the headers on without the heads, and vice versa.

 

Alright heads it is, but I agree it would be easier to do both at the same time. I will post numbers for the heads after its tuned.
