I Need Help Identifing These Big Block Chevy Lifters

[@thereluctantgearhead4544]

Thanks for the shout out man. Looks like ya have some Isky "Red Zone" lifters on the left, around $800 bucks a set of 16. The units on the right look like Howards "Max Effort" retro fit lifters, they go for around $600 a set. Also looks like some Morels in there too. The OE style are whats used in the LT1/LT4 5.7 SBCs in the mid 90s. They are durable lifters too and if they are in good shape they are totally usable. Better than new china units. Thats a big chunk of bread worth of lifters ya got there, probably couple grand worth, good swap for that intake. All them retro fit rollers are expensive as hell, and the Delco GM lifters are pretty high too. Nice score over all.

So you should of used a factory roller to show everyone what you were talking about with the oil hole. The factory lifters are shrouded and would of made it clear. The Reluctant Gearhead might of been able to give you more info?🤔👍
