Never done this before (no header gasket)

I think you'll end up with a big mess and leaks. But that's me. If you're worried about the clearance, I would pull that header back out and knock that corner in some on the shock tower. It's not like you ain't modded the body to get the headers through, so what's a couple more dents? I'd run some good gaskets if it was me. Just my friendly opinion.
Not worried about clearance, I have all I need, I am looking to see if anyone has done this, I do not want to pull and replace if this new way is working, I have some good Reemflex caskets here, but my son and a bunch of other racers do this and not get a header leak at all all season Rusty, I watched a video where an old fellow did this to his 302 steal engine and Tti headers in his 65 mustang, no leaks in 3 years, so he did it to his 68 Chevy 350 truck.
It just amazed me. And thank you once again RustyRatRod

Mikie don't want to drive Victoriato town and back(20miles) and start hearing an exhaustleak

I had a set of Pro Parts headers that would leak no matter what gasket was used. cleaned them up and after listening to my circle track buddy. put some ultra grey on them and let it set up a while before bolting them on ( with gaskets I'm to stubborn to try it without ). never leaked again.
Thank you, did you put the sealant on the header side or engine side or both ? Thank you for your reply.

Had a set of hooker headers on a small block that would always leak at the gasket. After 2 sets of gaskets failed I used Grey rtv without any gasket, after that they never leaked again.
thank you, this is what I am hearing, thank you for your reply.
