Sometimes you get caught in the drudgery of installing piston rings, and you just gotta put the thing together for two seconds to keep the end game in sight.
Yeah, I have to take it apart again to finish the last four pistons, but I needed the boost this sight gave me. Kinda bummed the seats are 'pulled in' for the 1969 302 heads, so I had to use a set of E7's I had on my other 302. I'll get the seats put in on the old heads later on down the road (the shop wanted $480 for both, which is a bit much to stretch since I'm not making as much as I was last summer).
Note: Some of these parts aren't final (The Cobra valve covers for instance, fan spacer is missing, that harmonic balance is actually cracked, etc).
