Trick Flow heads on 5.9 Magnum block

gzig5 said

I think there is some confusion here, maybe it is me. Unless you are proposing using flat tappet lifters in a Magnum block.

The AMC flat tappet hydraulic lifters are for using Magnum heads on LA block. AMC lifters will supply oil to the pushrods. If you have an LA block, there is no need for that because the TF heads will get oiled the way they were designed to, through the block.

If you're using the TF heads on a Magnum block without the passages to oil the heads drilled in the block, you can use the stock roller lifters or other roller lifter that oils the pushrods with the Comp ultra pro magnum rockers and oil the rockers through the push rods.

I probably did complicate my response with the AMC comment. My interest is running the TFS heads on a magnum block. And with a roller cam, so yes the AMC reference was incorrect.

To rephrase. Magnum roller block. No oil holes. TFS heads (shaft rockers).
Q: Are the comp rockers an alternative to the big $ set of Harland sharps in the TFS book?

I "think" I'm asking the same clarification question as the OP. I'm just surprised that these comp rockers are the magic solution to "how do I run LA heads on a magnum?" Tfs is irrelevant no? Have heard of the external oil lines. (As above) Never heard of rockers that simply have through-oiling to go from lifter, to pushrod, through rocker, into shaft.

Maybe I'm way out in left field. Trying to learn for my own knowledge, and possibly explore it for a HO crate offering.
