I run what is called a metered lifter. Because it is my understanding you Do not what nor do you need a high flowing lifter. Reason being is it can just flood the top of the head/block and Not leave much in the pan?? And I'm pretty sure this may become even more of a issure if you running a high volume oil pump. Which also is not realy needed The stock pumps are just Fine even in a high RPM motor. So my 2cents on this would be stay with the stock lifters, Or give Tom Langdon a call At stove bolt. Hope this helps
