Brand new Head TB42EFI ?

[JoshyGQ]

Hi Guys,

Just Purchased a brand new complete head for my GQ (model in title) im ripping out the gas system and running straight petrol for when i have it back up and running.

Just wondering which oil i should now run? I was previously running 20w60 penrite but have been told that i should run thinner, any suggestions based on straight petrol?

Also any suggestions on anything else i should change whilst everything is out? Ive purchased

New radiator hoses
Thermostat and therm gasket
New head bolts
New studs
New oil filter
New head gasket and new gaskets for exaugst both sides
New Drive belt
Sump gasket
New spark plugs
