How to determine what size primaries you need for longtubes headers?
Well, Im getting ready to buy my 2nd set of longtubes and Im wondering how do I choose the right size. My choices are 1 3/4, 1 3/4 to 1 7/8, and 1 1 7/8. Most of my mods are in my sig., but Im planning to do a bigger cam real soon and heads will also be in the future. What size do I need? Thanks.

Personally, I want to go with the stepped headers, but I just cant justify the price. What kind of disadvantages/negative affects will I have using the 1 7/8 with a big cam stock heads? I will be doing heads later on and I might even consider nitrous, but that will be a long time from now.

They would offer great performance, with no draw backs that I know of. My friend is running 1 7/8ths on his heads, and cam, and everything else 414 LS1 and they work great.

It was my impression that 1 3/4 is good for stock cubes/near stock hp, and 1 7/8 is for 383 and up cubes or serious ponies....am I waaayyyy off track here or no?
Also....who sells the stepped headers?
