I currently have some headers that are warped the f up and was going to get some new ones. Im looking at some speed engineering. They sell both 1 3/4 and 1 7/8 size. What size would best fit my application. Current mods are 862 heads ported and polished with ls1 intake valves. Texas speed stage 2 212/218 600 lift and a tru dual exh. Thanks

1 7/8 and dont look back

Search any dyno sheet you want. The "torque loss" myth isn't proven true based on dyno's and you will see better gains up top: 5-7hp

I have a 5.3 with the .550 version of that cam with TSP 1 7/8 and she rips

His 5.3 rips so hard it tears up 4l60s!

Well I mean, 4.3s can do that too
