I'm optimistically thinkin' he may not have the proper restriction in the supply tube to the rockers. I think he said he replaced it....
I know the shop where he had the work done, and they are a way oldtime automotive machine shop, family owned. My dad had his 230 rebuilt there in the late 60's, and they have done work for me on my 235 in the 70's and 80's, and most recently they did a little machine work on the engine of my '37 John Deere.
But anything is possible, and they do mostly build race engines these days....
