Pushrods rubbing heads

10 bolt BAE fuel heads, blue stands, stage V intakes, dual taper pushrods. Intake pushrods rubbing the liners.
Question: will the manton tool steel straight 3/8 pushrods hold up to a whipple? Is it possible to bore the holes out and put larger liners where the intake pushrods go thru?
Need to fix before liners get too thin. Putting chips in the oil filter.
Any thoughts?
I have more money in them than they are worth.

 

I would give Manton a call they are great people to talk to..and you will learn so much from them..I had the same problem and they took care of it, I think my spare motor used the bob newberry push rods and solved the problem..Dave

 

i had the same problem with std deck with brad 5 ful heads. i use mantons double wall 3/8 straights with a comp.250 taller lifter cup. no mods to the head. seams to be working fine. spring pressure is 400 lbs and only turning the motor 8000. hope that helped..
