Camshaft/valvetrain question

Hello all,

I originally made a purchase on new valve train equipment, and now in the processes of assembly. Thats were I need you help,

 

Here the Product that I have.

Isky Camshaft Grind # L-480 ( cam lift .327 / valve lift .480 / dur 280* )

Springs part number 7005 (performance spring)

Retainers 1624-st ( Steel retainers)

 

Problem that Im running into is. The retainer itself is much deeper over its factory counterpart. What I mean by this is the cup that holds the lash pad is deeper & have a much higher side. I know I have to get larger lashpads for this set up sence the factory .120 disappears inside the retainer, Is this normal. for retainers having a deeper side wall? also were might I find lashpads at a good price?

Thanks for the help

Ron

The retainer is deeper because thicker lash pads are required with that cam.

As for Lash Pads, Isky's thickness recommendation should be a good starting point for the head setup.

There was a thread somewhere on here lately containing a good explanation of lash pad selection.

Nissan Motorsport has lash Pads - You might also want to give Dave at Arizona ZCar a call.

I'll look up some URLs tomorrow if you need them.
