I thought about that, but then I remembered that roller lifters don't spin, how could the pushrods?
I wish!

 

The pushrod isn't welded to the lifter it should still spin, so should the valves.

Edit. Unless on the valves i'm thinking of valve float. in which yea,, they spin

 

I'll ask my builder about pushrod length when somebody who knows for sure can answer the above question.

 

did you come up with anything? i have a weird ssllliiidde dink sslliidde dink noise. but its fast, i pulled each coil pack connector one at a time and it didn't go away. if you free rev it (park/neutral) it doesn't do it very bad but soon as you put a load on it IE slight stall or take off it starts loud. it won't get louder and louder just faster per rpm.

 

Not yet, I am making arrangements to get a spare vehicle while I have the truck down. I expect to start next week.
