Topic: Sonata Gasket Kits Sonata V6 3.0i 1997 GLS

Where would it be possible to obtain full head gasket kits for our Hyundai Sonata v6 3.0i 1997 GLS. I cannot find the original part number for this set. Every kit I find for sale under this heading informs me that it is not suitable . I wonder Why? Reg No. P856XHO. Any advice please.
