First year for hydraulic roller lifters was 85, mid year introduction. EF is wrong. You can run regular flat tappets if you want to, BTDT. In fact, if you look into it the 87 318 2bbl (for example) came with a roller cam, whereas the 87 318 4bbl cam with a flat tappet cam, same block though. Other things are different but not the block. Now you CANNOT run an OEM roller lifter in a non-roller block, but that's another issue. You will also need to run the flat tappet pushrods.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

I'll shoot for 9.5:1 CR instead of just under 10:1 as done in that old article. I'd get (.040") quench if you can keep the SCR where you want it. It is a significant bennie.

If my fuzzy memory rings true In this book https://play.google.com/store/books/deta...CFcEQPwodN8kMswhttps://www.themotorbookstore.com/how-to...AiABEgIt8_D_BwEThere is info on lighter, improved durability, and lower friction, hydraulic roller lifters that were created for Viper Aluminum V10s but can be used in sb v8s, as can slightly longer V10 con rods that give tighter quench. Later year Viper V10s went even further and changed to smaller diameter, even lighter, roller lifter designs. Willem Weertman wrote in his book Chrysler Engines that the earliest iron and aluminum V10s used Magnum 5.9 V8 pistons for cost reasons. In the 1995 Ram pickup FSM the 5.9 Magnum v8 piston drawing are wrong, but the iron V10 chapter has correct piston drawings and specs.

Hughes and Lunati have "retro" roller lifters you can run in LA small blocks. They are designed with the oil hole lower on the lifter. Hughes told me most of the issue with the oil hole possibly being "too high" for an LA block is a 340 block. Also told me they never saw an issue with a 318. If you go on the Hughes website, they have pictures and an explanation, more in depth which I mentioned.
There are also .028 head gaskets at a decent price or you can get a .027 at about twice the price.
