How made the pushrods right axis from JDH standard crankcase to 8 valves heads.

The pushrods a 2cam are not in the same axis as the push rods of 8 valves. A  good friend (Serge Cruz) made ​​push blocks that put the pushrods in the right axis.

It also included a small seal to minimize oil leaks.
A beautiful work. Thank you Serge.
