I wish I could tell you that! The EB heads are a 'semi-open' chamber at only 110cc. Not saying the SRP's are th ONLY slugs that work (the article I posted used Speed Pro's) but 22cc's is a good sized dome with a small chamber head. All I can say is measure, measure, measure test fit and measure again! No one wants to slam pistons into a valve! I am curious to see what you find out. I'm taking my block in this week for machine work, so hopefully I'll be putting my junk back together soon and can let you know what I find.
