I have several of them, and even a couple of them are hooked up!Maybe a tach would be good

No, those don't need wiring, pooky..Talking about your hearing aids?

Hadn’t thought of that John. I’ll try that next. I think I have a fewFind a steel donut gasket and put it in, cheaper / easier that a collector change.
Right now I'm just pissed this never occurred to me to try...The collectors on the headers in my old truck were worn out / rusted / bent and I couldn't get gaskets to seal, the donuts fixed my issue.
Let me check tomorrow. I think I saved the part number.
I’ll look into those. Thanks@Bent77 these are solid metal, not the typical compressed gray stuff like most donuts.

Are those what you use with your Sanderson headers? (I hope I'm remembering correctly that you have those headers on your 454)@Bent77 these are solid metal, not the typical compressed gray stuff like most donuts.

I have more than that on this injection systemI do have Sanderson’s but so far I just have their gaskets with no issues. Keep in mind though, I probably have WAY less run time than most. I probably only have 200 miles on the motor.

Been looking at those already. Probably try the biscuit before I go awolI have replaced the collector all together. Cut the collector off and used a reducer welded to the exhaust side and slid over the header. Then used one of the two bolt band clamp like semis use to seal it up on the header. No leaks and better clearance.
