personally I wouldn’t spend that much money on a set of 220 TFS heads ,and then cheap out on a set of 1 3/4 headers
if looking to get the most out of that engine,you would be better off with 1 7/8 just my opinion
the highest horsepower Ls 2 NA car .I’ve seen on Corvette Forum
had 227 TFS Heads with 1 7/8 headers I’m thinking it was making around 527 rwhp and around 480 rw torque
my old Ls 2 made 509 rwhp and 447 torque with cnc ls3 heads 1 7/8 headers
IMO your wasting your money buying a 1 3/4 headers for maximum effort LS2 NA build
and looking at your parts list looks to be maximum effort ls2

The 1 3/4 were already on the car when I got it, I’ll be going to the 1 7/8 soon, what kind of gains do you think I’d see stepping up to the larger ones after looking at the graph?
appreciate it!

your TQ #'s would be much better with 1 3/4's before giving any opinions you need to do some serious reading, your HP and TQ should be very close not47- 56 apart. ever watch "engine masters"?

Eric Weingartner video (his dyno results)
