Ran a compression test and got between 125 and 145 for all Cyl. Cyl 1 had the half of the butterfly valve stuck in it which was removed before the test. Cyl 1 was at 135 which was right in the middle.

So, considering I have to move out of my house (Putting this one up for rent) I will need to put her back together for about 6 months. Thus I am only doing timing and the lower plenum. Once I get moved into my place (which has a shop) I will need to pull the heads and consider a rebuild. I was not able to find the rest of the butterfly valve and the previous owner drove it like this for over 5k miles. I hope it went into the exhaust!
