Pushrod question

I’m not an expert, but I’d like to upgrade to a set of TF heads. From the research I’ve done, no it won’t be an issue. Assuming you have an LA block, and the correct TF spec’d Harland sharp rockers, you can retain shaft oiling and use solid pushrods. The TF’s will work on either magnum or LA blocks, depending on valvetrain oiling.

Edit to add: If you are completely switching to pushrod oiling, I think you’d want to restrict the oil going through the deck to the shafts, that’d be a lot of oil going up top.
