I have some Manton Pushrods that are 7.625 Length, Ball/Ball never used if they will work for you. Hardened Tips & Shafts that are Oil Thru. I am pretty sure they are what you need with the RHS Heads. As long as your adjuster is a CUP style on your rockers.
The ones I got for this motor were $200.00, my spring pressure open is around 510 lbs.
Terry at Manton says with the turbo's he always goes thicker wall because the exhaust gets hotter on boost. He actually wanted to go thicker on the Exhaust Pushrods and I would have had a Split thickness but after I told him my intended use he said it should be fine.
