714banshee380 Posted August 12, 2008 Report Posted August 12, 2008 I just want to remove my head to see if there is any wear/damage on walls and pistons. Do i have to prelube bolts when i reinstall. thanks Quote
jharader Posted August 12, 2008 Report Posted August 12, 2008 Just take it off, ive never "lubed" a head stud, i have put anti-seize on them b4 but chances are you wont have any problems getting them off in the future so eitherway your cool. Check your compression b4 and after just cause, torque them to the required amount in the correct order.... :thumbsup: Quote
mdhc500 Posted August 12, 2008 Report Posted August 12, 2008 (edited) Yeah, just clean them off good with a brass bristle brush and use some anti-seize. You should be good. When you torque them back up to it in a figure-8 pattern working from the inside bolts out, in three stages. 10-15-20 ft lbs. Warm it up to operating temp and re-check-torque. Also spring for a new gasket if its the stock head. Have fun... Edited August 12, 2008 by mdhc500 Quote
KlotzBanshee Posted August 12, 2008 Report Posted August 12, 2008 Warm it up to operating temp and re-check-torque. After the motor is completely cool of course, never torque down when warm or hot. I'm sure that Quote
714banshee380 Posted August 12, 2008 Author Report Posted August 12, 2008 THanks everyone for input. well I prolly won't get to work on it until ALL my parts come in so I can put in new pro design shaft, i have coolhead so the gasket should be fine. thanks everyone Quote

714banshee380 Posted August 12, 2008 Author Report Posted August 12, 2008 depends on your elevation and the size of the domes in the head. elevation at my house not sure but where i ride (glamis) sealevel. and 20cc dome Quote
Onesickcrewcab Posted August 12, 2008 Report Posted August 12, 2008 elevation at my house not sure but where i ride (glamis) sealevel. and 20cc dome Check out this link. Scroll down towards the bottom. it gives you a chart stating around where your compression should be for your dome size and elevation. http://www.nossmachine.com/banshee_heads.htm Quote

Just curious, how do you guys check your compression? I bought this compression tester at harbor freight a while back and I haven't used it yet. I heard they were'nt very accurate but I had already bought it so oh well. Quote
mopar1rules Posted August 13, 2008 Report Posted August 13, 2008 the reason some people apply lube to the head studs and nuts, is to reduce the friction between the stud threads and the nut studs, for a more accurate torqueing of the nuts. this is called "wet torque". some may apply the lube so the nut doesn't seize to the stud.
