Not a bad idea, it is just a simple tin plate that keeps the lifters from turning and in place.
Can buy stock replacement aftermarket roller lifters for like 10.00 each to go with that mopar 318 spider plate. That is only 80 some odd dollars for roller lifters plus shipping.
Just want to make sure the roller lifters stand proper in the LA lifter bores with the roller cam in there.
Stock replacement '90 318 Roller Engine Pushrods, Oil hole through the pushrod oiling. They are in short supply right now at Rock, but the part numbers are there to buy elsewhere.
