What Header Gaskets to use????

[cmadz71]

I have a 98 K1500 with 5.7L. I have JBA headers and need to replace the header gaskets. Everybody has square or round header gaskets and I don't know which ones to use for my truck. I talked to JBA and they made headers for my truck in round and square style. I don't want to take the header off to find out which one I need b/c i'll have to wait for the gaskets to get here and will have to put the header back on. Any help would be appreciated.

Get a set of each and take the one back you dont need.

that is what I ended up doing. I ordered a set of each from Jegs and they'll be here today.
