[FMFBlaster240]

supposedly 20 -25 ft lbs. but last time i did them to spec they came loose and blew a head gasket, last 2 i did i evenly in a star pattern cranked them tight, havent had troubles yet

18 footpounds if I remember right. 25 will pull studs, then you will blow gaskets. torque in 5 pound incrementsusing a star pattern.

it's 20 for head and 25 for base, and my arm torque wrench (closely related to the ass dyno)
said cranked tight is perfect

and I sugest time serts when your armstrong model torqe wrench strips the aluminum threads.

I had torque wrench adjusted to 21 ft lbs by mistake and pulled one stud through head. Be careful and torque to 18 ft lbs. Retorque also.

the clymer manual says 20 in a star patern. then retorque a couple of times durring break in or just check it a few times the first few times you ride

If it was a brand new head gasket, and the studs pulled torqing it, take the gasket and put it on a gas stove on high untill it glows or a propane torch and it should be good

damn phragle... i already ordered a new gasket. but it turns out the guy i got the blaster from had already installed heli coils and i pulled the coils out. so i just re tapped it and was able to thread new heli-coils
