3/4" bolts will work.

Good luck getting those Hooker shorties installed. they are hard to get lined up. But, it can be done, just be patient.

Just something for you to consider, somebody mentioned this right after I installed mine, hope I'm in time for you.

Anyway, get hex cap bolts for the headers and it should be much easier to tighten the little suckers than traditional header bolts.

The hex head bolts I am going to try aren't "header" specific bolts. But they are a high quality bolt. I can get them cheap, so if they work on my car I can get you a set. I'll let you know Sunday how they worked.

My EM header's flanges are pretty thick and after the gaskets there's not but 3-4 threads in the aluminum heads (with the 3/4" length bolts), the 1" bolts give another 3-4 threads and make me feel better.

I like the 3/8" 12 pt bolts. I use my 1/4" drive ratchet set to torque the bolts down.

I ordered the Percy header gasket for the chevy small block, square port. My friend reminded me LT1's are d-ports, so I was wondering if these will still fit, they look like they would.

Default D-Port Gasket

Considering the price of Percy's header gaskets, and the difficulty installing the Hooker shorties. I would get the correct gaskets and try to do everything right the first time. You won't want to repeat the process.

I used the Stage 8 system, the backside bolt on # 8 exhaust port was a pain in the azz, but the hex heads help.

The Fel Pro 1406 gasket has over 1000 miles and 16 1/4 mile runs on it.
