304 with fenderwell headers - Which gaskets and bolts are best?

I have a 74 CJ6 with a factory 304 V8. I am going to be running fenderwell headers on it. What gaskets and bolts are best to try and prevent leaks? i know headers are notorious for leaks but I want to start with whatever works best. I have heard stage 8 locking fasteners work well but is there something better?

I used Percy's gaskets and ARP bolts on my '72.

My first ever set of Stage 8 have been great for me so far.


I have removed and installed the headers since that picture was taken. So yes, I got the one on the left clipped on all the way.

Coiz,

I've never seen those stage 8's. The one's I ordered would not fit between the port tube and hole. I'll need to find those! Love the stage 8 stuff!

Thanks for posting that!

Edit: these are the one's that wouldn't fit my headers: http://www.summitracing.com/parts/st...merican-motors

Edit, Edit: I see your flange has more space than a 304, so those probably wont work either...oh well.

I did have to grind and trim a few of the tabs to fit, they didn't all have that much room. They will obviously contact the header at some point if the bolt does start to back out since that's how they work.

I'd say get the kit, install the bolts and torque them, drive it around for a few hundred miles, torque them again then install the locking stuff. Just modify each locking tab so they fit and try to contact the tube as soon as the bolt tries to turn counter clockwise. Just keep them numbered if you ever have to take it back apart. Who are we kidding, its a Jeep, your gonna have to take it back apart.

I thought about grinding them ... but thought they should fit. So, I sent them back. I do hate checking my header bolts every month or so.

So, with that said, and having someone, that I respect, grind them... I think I may reconsider...Thanks! I just bought the stage 8 dana 30 spindle bolt kit that I'll be installing next week:

Sorry OP...I hope I'm not detracting from your Original Post...
