LS6 Intake or Ported 853 Heads
LS6 Intake or Ported 853 Heads Alright, should I go with the LS6 Intake on my 98 LS1? or the Ported 853 Heads?
Currently I have a 98 LS1 from a SS Camaro in my 96, its a M6 setup, current mods are below. Just wanted to see from which I would see more gains from. Not sure how well a set of ported 853's would flow but hopefully they would flow pretty good. Does anyone think they would flow like LS6 heads? The heads were milled a little I think to raise the compression. My car has the stock 806 castings which I heard, stink.

heads will net you a larger gain but it will cost more and take more time...since you have the 806 heads you will need center bolt valve covers and brackets as well as gaskets, head bolts, etc. Also if you take all that time to swap the heads you might as well throw a better cam in there. Honestly a head swap is on a totally different level then swapping the intake is and really isn't comparable. A intake swap will only typically gain about 10 hp while a head swap can gain 40 or more depending on how well the heads have been ported but like i said there is ALOT more involved in a head swap
dont know about the flow #'s or anything buy if you have the cash and can go without your car for as long as it takes for the heads then i dont see why not. ls6 intake is nice but if you can do the heads then you mnight as well.
as far as down time, I will have heads, get all parts together to do the swap and would take me only some hours to do the work so no down time for me really, Just patience.

I would say heads. I had some 853's that I had ported at one time. It made one hell of a difference after I installed a 222/226 cam. It was about 70rwhp difference and probably around 25-30rwhp with heads alone. Intake will be the bottle neck at that point.
Or what the hell, do both. Anyways, moral of the story, yes PORTED 853's will flow a lot more than STOCK ls6 heads...
alright, got the heads in my hands, the porting is badass, fully ported and polished, will post pictures of work on here. I think its the way to go for now. I play on installing the heads when I get the valve covers and brackets but while im at it, will install the LS7 lifters and probably some good springs. Then comes the cam and intake.
