And if you upgrade the relief valve spring in the oil pump, it will increase the oil pressure at idle and improve 7M reliability and life span. Upgrade the stock oil pump hose to a larger steel...

While my engine block and internals are sitting in my storage waiting to go machine shop, while I wait I'm shopping around for parts. Should I go with composite head gasket or MLS? I plan on just doing a stock rebuild on this 7M-GE supra no power adders (stock horsepower) and factory red...
