This is a 318 roller block that will be used with aluminum heads. Pro Comp or Eddy, 4" stroke. Street use only. Doug Last edited by dvw; 10/29/19 09:25 AM.

Requires a hole into the head and a hollowed out rocker shaft hold down bolt. I think the PRW Stainless steel shaft rockers will oil through the pushrods and are probably your cheapest option.
