406 small block review
Wage92, Is this the 406 Scat rotating assembly from Ebay (Skip White). Does it have the Probe 14cc pistons with a compression height of 1.140? If so then your parts stack height is 1.875+6.0+1.140=9.015. 9.025-9.015= .010 piston to deck height. Now to get the quench of .040 you need a Cometic MLS .030 compressed thickness head gasket. Or any other brand if you can find it. This will put you right at the edge with a static compression of 10.588 and a DCR of 8.512 so you really need a tight quench. Still should run on 91 octane so if you are using 93 octane you should be fine. This is why all information needs to be provided in the post or a part# to verify the info.
