400/450 stroker....Cheap parts, lotta work.
Lordy, knocking all the burrs off by hand wasn't fun. And I had to do six of the bottom spacers again because they came out .035" too tall and moved the the pattern off center towards the exhaust port exits and spread it out to .050".
You can kinda see the pattern on the left valve without the correction kit. It is off center towards the intake port openings and .110" wide. The valve on the right, using the correction kit, has a sweep pattern of .040" and is centered on the valve tip. Bad picture but it is the best I could do for now.
