I put shorty headers on and hpipe, the h pipe is bolted tight to the headers and sounds like a exhaust leak. I took smog off to pipe. Could the leak be the back of the heads ?

If you removed the smog pump tubes from the rear of the heads and didn't close the hole with a bolt or threaded plugs, I would believe that's where your problem is.

I didn't remove that bolt yet I sealed it at tube welding it at the t for now. I bought plugs from lmr. I used regular grade a bolts to bolt the two together should I use something different

Deleting them wasn't bad you Don't suggest it
No, not at all. Almost zero horsepower gain, but the potential to create all sorts of other issues and ECU trouble codes is now present. The pump is only really active during cold start and light cruise. They practically free wheel any other time.

Deleting the pollution equipment was one of those mid-70's mods that should have stayed in the 70's when pollution systems actually hindered performance. There's nothing really at all to be gained by deleting it on a Fox body.

Even my 500hp stroked and poked blower car still has all its pollution hardware.
