273 commando cylinder head bolt torque specs ? same as 340 ?
all i wrote, i in regards of torque is from personal experience, i have always used moly lube on my head bolts and main bolts, by using moly lube , you will have more clamping pressure without distortion. i used on my 273 and my 340,.i know arp wants 100, lbs, you will pull block deck up creating a deck with low places and high places. also gasket seal problems. first time i torqued my 340 block at 95, it bell mouthed the top of the bores, by .006 i retorqued it at 85 had no bell mouthing of bores. my 273 was 11.1 cr, my 340 is 9 to 1, cr. i run stock eliminator with it. just food for thought,
