340 street build help from experienced input

I do not believe that to be accurate. You would need to contact the company on where the measurements are take a new if the lash is included and accounted for.
Howard’s makes solid rollers as small as 229 at .050. After lash even smaller than the hr at 224 at . 050
Will look into. I’m guessing the LSA is still higher though unless it’s a custom grind. I understand what these gentlemen are saying about closing that angle to get more cylinder pressure. Is that not what they do with making rattler, thumpr and whiplash cams for low compression stock bottom ends?
