Is it worth the extra effort to build equal length turbo headers for a street motor? If so what's a good rule of thumb for determining the length?

Thanks,
Kevin

are you running a 23 degree headed small block or ls1? or?

ASM injected 454. GM ovalports. Hope to upgrade to 540 with BIG heads after I finish the rest of the car.

Thanks,
Kevin

i would not worry about it to much you wont see any huge gains with the set of equal lengths with the twins on a big block you going to have more power than you can handle. what material are you going to make the headers out of?

Nope from everything i've read and studies you will not need equal length headers.

I'm using 316L. 3/8 flanges, 2" schedule 10 for the tube and bends. It's heavy stuff but I can walk next door to where I work and get the bends for around $5 each. It welds, smoothes, and polishes easy. The ID may be a little large at 2.15" but my next step down is 1.75" ID which I think is a little small for the 540 when that happens.

Thanks,
Kevin
