Default What header gaskets to use

I got the LG header system with cat delete. I heard that the kind of gaskets they put in the kit are known to leak, I wanna use metal ones but the stockers port holes are not big enough like the headers. Is there any kind out there to use.

Get a set of stock F-body ones. Their openings are bigger and will better match your header ports.

I ordered factory gaskets for a 99 C5 and they were the big round ones unlike the oval port 2001 Z06 that came off my car. Probaby same ones as the F body cars. They are 3 layer steel gaskets. They sealed my LG LTs very well on my car with only half the bolts in the headers. Don't laugh, I just bolted them up with a few bolts to fit the headers and exhaust, they are off again changing heads now, but I did run it enough to move the car around a bit and they sealed very well.
