With the combo I am about to have going, how much would a set of heads help? I don't want a bigger turbo, just want to max out what I have with alcohol.
$1600 for a set of GN1's is a little too much if you are going to stay with the 44. You can get 90% of the perf gain by having a good shop that knows what they are doing port your iron heads for you for $6-700, IMO
Would the GN-1s work with my current combo? I have another block that will be built to run a low 11 or better that could use those heads. I'm thinking a couple of years down the road, but I don't mind spending the money if it would help me out with my current set up.
They will work, yes, but they will not be money well spent. I would wait and see how TA performance's new heads perform, and then decide which ones to buy
I'm am going to wait. It will be the summer before I do anything, so maybe the TA heads will be all everyone hopes for and any bugs will be worked out by then.
