Headers for a LQ4?
Just bought an ATK LQ4 head/cam motor and deciding on headers. Specs on cam are 216/224 551 lift 114LSA. 9.5.1 compression with LQ4 heads. Would I benefit from 1 7/8 primaries or should I stick with 1 3/4. Going with TSP header and Y combo just need to figure out what size to go with.
Thanks

Going into a 01 Trans Am. 4L60E. Hopefully the transmission and rear end can take it. And i went with some Speed Engineering 1 7/8th with a TSP off road Y.

If you plan on a 408 in the future you might as well get the 1 7/8 so you will already be set. I am planning on getting the atk motor in the spring for my truck so it will be nice to see what #'s this puts down to the wheels.

Thing is a freaking torque monster now and pulls surprisingly well till about 6300. It has already taken down a 2015 5.0, 2012 Camaro ( I did that with bolt-ons only before), and my buddies stage 2 sti. I am pretty happy with how it turned out. Don't see any bottom end missing with the bigger primaries so I guess yall were right.
