chilton 273 318 head torque spec says 85 ft lbs in low compression engines but does not mention what it would be for the commando ....just says 273 318 .. it says the 340 is 95 ft lbs. wouldn't you think the commando with 10.5 compression will be torqued at 95 ft lbs also like the 340 ?.
getting read to install my commando head back on the 273 .. It blew the pass side head gaskets 3 times already.. last time I had the heads milled make them flat.. they were not that bad only too off .002 ".
block appears to be flat . I check with a few different straight edges. used mr gasket 1121 head gaskets .. these suck the ring is so big in the bore, there is not enough meat to even clamp too. the fire ring is almost in the valley. that's where it blew last time .
arp bolts will be used this time.
I had the 1121 head gasket torqued to 95 ft lbs like a 340 with high compression.
opinions ?
