Get on the phone and find a REAL Parts store and get the kit
Try it Torque a cold motor and try again and nothing fancy like
loosening the bolts and then retightening em....that will get you trouble Just pull each one up!

No please listen....If you replace the gasket Torque and then don't put any water in Wait over night and torque again then add coolent and run to over your operating temp USE a little cardboads to part block the rad and torque

Drive it a couple hundred mile and check the whole mess

Get some KW coppercoat spray for the gasket You'll find it at the same auto parts story you get the kit at AND follw ther directions on the can

There no need to check the block for straight just get buildin your new engine quickly OK?
