SBF Tech - Need sparkplug info for GT40X heads...

Guys

Looking for the correct plug for my dad's engine. It's got the aluminum GT-40X heads on it and FRPP recommends a AGSF-32C spark plug. Well that plug is a tapered seat plug and the head looks to be machined for a gasketed plug. Any ideas which plug these heads take?

An M-6049-X306 aluminum head uses AGSP32C plugs and they are gasketed if I remember correctly.
Maybe you are mistaking the P in the part number for an F.

Edit to correct part number.

M-6049-X302 uses AGSF-32C plugs. (These are discontinued but are still out there.)

M-6049-X306 uses AGSP-32C plugs.

I looked and had it written down as AGSP and mistyped it as AFSP, sorry about that, I will edit my post above.

Thanks. I'll go check the numbers again
