@seattlejester yes, I suppose it is cylinder number 6 that is featured here. Good advice on the flushing of engine after racing. Quite frankly we're complete mechanical amateurs and surprised in our attempt to get this engine back in shape for a THIRD attempt at a Lemons finish. Gluttons for punishment.
Sorry to say that I don't have compression numbers before head removal. Amateur mechanics at work. The day before we pulled ithe head I purchased a leakdown kit from Harbor Freight and didn't even bother when I saw how much water was mixed with oil in our poor engine. A trusty Sears compression kit was also standing by but in our naivety we just didn't even bother. Next time.
LA Machine Shop is two blocks from my house and I'll take the head there on Monday morning for a professional eval. We'll see if NewZed correctly diagnosed a warped head/blown gasket on the other side of the internet. Thanks to both of you for offering sage advice to a bunch of idiots.
