I'm building LS1 383 and I'm trying to prevent valve float from happening what can I do to my lifters or what is a good brand recommendation? Any help appreciated. Daily driver cam 224/228 567/571 114

 

The way to prevent valve float is get strong valvesprings that match your cam specs.Lots are using the stock lifters with good luck,theres nothing you can do to the lifter itself.Also lighter components such retainers and valves etc.

 

Well there is the Comp "R" but with a cam like yours I wouldn't venture there.
Comp 850-16 replacement lifters are a good way to go. $ 199.00 or less.
