Total "bill of material" for Aluminum head swap / Advice on where to save $ welcome...

Late to the party here. Going back a few posts, Trick Flow specifies Harland Sharp rockers on a magnum block because they are a LA shaft arrangement. You need to get oil into the shaft/rocker interface.

Magnum/AMC oil through pushrod arrangement only gets pressurized oil to the top of the push rod, then splashes the pivot point. Those particular specified Harland Sharps are made with a passage to get oil to the shaft.
If you have an early Magnum, with the oil holes drilled from cam bearings 2 & 4, you can use (almost)any LA style rocker. Factory style iron 273 adjustable rockers apparently don't work because the TF stands were relocated to correct geometry for use of roller rockers. My understanding (could be wrong) is that Mike @ B3 had a hand in this. Now the question is; which rockers offer the best OOTB geometry?
In later Magnums, in order to get around the oiling issue, some people are oiling the shaft with an external connection off of the oil pressure sender port to each head. I was going to go this route when I get there, but found oil holes in my Magnum block when I opened it up.

For what it's worth, the PRW stainless rockers have the same provision to take pushrod oil and direct it toward the pivot/shaft. Only issue I had with the PRW rocker was the adjuster threads having tons of burrs. I chased all threads an re-cleaned the rockers and they were good to go.

I don't know what decision was ultimately made here, as i see i missed this from January, but for the sake of future readers, the aluminum headed roller motor does in fact use a bare edelbrock casting, that we assemble/machine here. Also...you guys know how warranties work. There's the legal jargon, and then there is how we personally deal with warranty issues. You guys know i have your back with all that. We're a good company, and we treat customers right. Not like i'm difficult to find if you need me.

sorry i missed the thread, i think someone tried to tag me but got another "johnny" instead. take care

Can confirm. BPE did me a huge favor when I screwed up my own engine with my own stupidity. Unless the customer has done something extremely wrong, you can expect PLENTY of support from BPE and Johnny himself. The warranty/customer-service they offer is worth more than the cost of a pair of trick flow heads, in my opinion.
