Super Jet Protec Head 650 SJ install questions

K

Kryo

I have a protec head for a SJ650.
I've seen several similar ones, how can i tell if it is for the SJ650?
Does anyone know the O-ring sizes?
Are O-rings the only gaskets needed? If so, how does the water jacket seal?
what would be a good starting to set-up for the jets on the carb?
i am running a coffman sizzler & sbn44 carb.
Thanks for the help

I just installed 2 of these one on mine and my friends. There are 2 different 0-ring width's mine was smaller them my friends. But dont buy them from protech its a rip off. Get them at mcmaster heres the part number 5267T57 this is for the smaller width. For the water jackets i used premtex high temp sealer and a little on the o-ring to hold it in place.
