Just wrapping up a Big Block Chevy install in an 86 442. Used Hooker headers for a big block/Gbody. The passenger side header hits the frame and will not allow the header to seal up against the cylinder head ( it's a 1/4 inch off the gasket)? Hate to start hammering on a new set of $800 headers?
Guessing I am not the first person to hit this issue. Any suggestions before we get violent on the #2 header tube?

Thanks for your help!

Never did it with a Chevy I did use hookers on my bbo in my 87 Cutlass and they fit beautiful I would think the quality for a BBC would be the same or better because Chevy is more popular and wide spread I'm shore someone here has done it

Are these 2241's if so I have installed these on multiple BBC Gbodies and only ever had to trim the driver's side mount nothing more.

Probably raised exhaust port heads, never had an issue with hooker swap big block headers....

If you are using solid mounts there is 2 different heights mounts.

If they are the 2241's then those are the exact headers I have on mine. No fitment issues here but they are a pain to work around. Maybe you have the wrong engine mounts or ended up with a faulty pair of headers?

I used 2455s on my big block swap but the dart pro 1 heads with the raised exhaust ports really threw a wrench in the mix.
