IRCC the plugs are Bosch Platnum R3's.
Yes there was alot of oily mess in the combustion chambers when I replaced the valve seals but I cleaned everything up before I put it back together. I also thought about the pre-ignition but now that everything is clean I shouldn't have it with only about 30 minutes run time since the seal work.
I am going to start chasing a vac leak and maybe pull the carb off and see if a jet is clogged.
Thanks, those numbers will help a bunch.
If it still is sucking oil, it looks like I will need to just breakdown and get a long block. I don't want to spend the $1500 for one and I doubt I can find a good running 351 locally that doesn't need work for a decent price.
