Thanks for all the help, we wound up doing compression checks and zero lbs on cyclinder 8...we tore the heads off and thought we would be lucky, found a bent exhaust valve there but what makes it worse the #6 cylinder wall was scored badly (deeper then 30 thousandths) and a small part of the piston was actually melted!!! So time for a big block crate motor and $7000.00 plus :-(
Oh well thats racing. Again thanks for the info.
