"Raw Power"
I hope to assemble my 340 engine in the near future with a mp 284-528 solid lift cam. The x heads were gone through by my local machine shop and are ready to go. When I bought the heads they had mp-p3412068 valve springs on them. The springs were good,so the heads were reassembled with them.
