1.7 Harland Sharp Roller Rockers
A few questions about adding these to a stock engine...
1) Do they work with stock valve covers?
2) Where is the power improvement?
3) Mileage?
4) Are new push rods needed?
5) What is the bolt diameter? 5/16 or 3/8?

Yes they work with stock valve covers (assuming you buy non-adjustables)
They have been dyno'd around 10 RWHP improvment, I noticed the difference.
My fuel mileage improved a little.
Factory push rods work.
Bolt diameter doesn't matter when you buy the non adjustable pedestal mount rockers,
