Thanks, I'll get to that hopefully here soon. Here's where I am so far. I found the old exhaust springs are different than the intakes (exhaust is on right in photo, intake on left), as well retainer caps. The new intake valve spring looks decent with it's different retainer setup , unlike the exhaust which looks too compressed (both new springs installed now on that cylinder). Thoughts? This engine gets more interesting every time I tear into it.
