I'm trying to find the right headers.........from what I understand, my lo3 has round exhaust ports. the guy at jethot gave me hooker pn 2460 that he has in stock, but as i look at a picture of them they look square. are they square, round, and will they work on my engine?

second.......someday when i put in a new engine (say a zz4), will these same headers bolt up to it? i don't want to have to buy new ones all over again!

The exhaust ports are round-ish, the header flange openings are square-ish.

That isn't a real problem. Ideally, you want the flange to be slightly larger than the port. The other way around is what you want to avoid.

They should work with the ZZ4 as well. It would be a good idea to check to ensure they don't block off any of the port, though. If they do, the ceramic coating will make fixing that a lot harder and more expensive.

awesome....thanks

one more thing....there's no ypipe, and hooker doesnt make any, so i assume im gonna have to get one custom made...but im not sure i trust some local idiot exhaust shop to do it....do i have any alternatives?

Yeah, cancel your order and get Hooker 2055s for the extra price you'll get a quality y pipe
