I think I killed my engine - 392W

I built the 392W engine for my 69 Shelby in 2004ish. Its been through some abuse over the years and has seen 3 different intake/head configurations. One time I missed 3rd on a power shift and hit 7,000rpm and bent an exhaust valve (~2007). Last year I put a set of ported 351W heads on it, removed the headers and went back to stock look for the SAAC 50 show. That raised my compression from ~11.25 to ~12:1. I have run octane boost in all of its configurations, and for the last 7 years, its been fed a diet of 91 ethanol free, base fuel +boost.

Cylinders 1 and 6 have been oiling the plugs for some time, but it got way worse after the head swap. Its now a constant smoker (not cool).The Duraspark keeps firing through most of the oil storm, and there's no knock or bang or clack...but I'm taking it down this winter. I'll be aiming for 10:1 compression this time :) Its not a date code correct block anyway, so I think Ill hit up Don Rush at WCCC for a date code correct M code to start my next build.
