Mushroombert... eyebrows? I know on the pistons the indentations are the eyebrows, but I didnt know that the cylinder walls themselves have eyebrows for valve clearance?.. I would have thought if that was true then all of the cylinders would have had them..? ..hmmm...

Bz.. yeah, I currently have a running 350 in the car, and plan on leaving it in till Im to the point of swapping over. My goal was to take my time, and build the engine right, once, ...then swap out the 350 and sell it to help recoup some costs (if theres any market for a 69 YE 350..)
