- By the mirical of the net, I present the exact solution.
-
- Use big block chevy "small" ( 5/16? ) intake pushrods to cure small valve
- lash problems with small block olds. I have these in my 69 Rocket 350.
- I believe they are 0.050 longer than stock. Use them for both intake and
- exhaust. The parts guy will wonder why you want 16.
-
- I too have a non-stock cam.
-
- For the better solution, call Mondello Performance and get the fully
- adjustable roller tip roller rocker kit with studs. 818 994 6910.
- This will cure large valve lash problems.
-
- I may do this soon, it depends on my cash flow.
-
- Also, if you buy the big block chevy intake manifold 12 point
- stainless steel bolt kit from ARP/Summit, you will find that it will
- work exceedingly well holding your exhaust manifold. Trust me. Just
- buy it.
