| You'll need to replace the valve retainers, too. |
| By Dave Shoe - 09/04/2003 7:59:16 PM; IP 12.2.11.131 |
The stock valve retainers are a long-lasting low performance type that consume too much space for high lift applications and are too weak for stiffer springs. The valves may also need replacing, since the lock grooves are positioned for the stico retainers.
You didn't mention whether the lifters were ebing replaced. To be certain, the new cam will instantly croak with high mileage lifters, and will also stand little chance of living id the lifters have even a few miles with another cam.
A full kit is the only way to go when changing from stock to performance.
Personally, I also strongly advise rockershaft end support pedestals, to help prevent shaft flexing at the end rocker positions.
It ends up coming to a moderately hefty price, but it's a lot cheaper and more fun than putting it together and learning the high lift cam is crushing the valve seals like I did.
