Sure, I've making valley plates for a long time. The valley plate will work a little differently depending on if you are running the 240 or 270 head. If you look at this article you'll see a bunch of pictures of how the valley plate works with a 240 head.

Andy I'm sorry I told you wrong. they are 240'still. for some reason I thought they were 270
I used 3/8 pushrods from Smith Bros. I didn't have any clearance issues with the pushrods. 7/16 pushrods will fit in about half of the holes but they rub on the other holes. I was thinking about moving up to 7/16 pushrods but haven't done the work yet.
Well Maybe they opened up the holes. These heads we got may have been some of the first one's out. Our 3/8 pushrods rubbed on about half the holes requiring them to be opened up. Another ?. We put in a Hughes solid roller with alost .700 lift and we had to do a spring change for it. This thing seems like its binding the inner spring cause it gets tough to turn over at almost max lift. These heads we built by a good shop so I'm sure they checked for coil bind . Is this normal on a roller to get hard to turn by hand with that much lift and such a strong spring?
