For those not familiar with Ted Wells, here is a extremely interesting HR article from March of '71, posted on HAMB. It's hard to read but, if you hit ctrl then push + until it's at 133%, it's easy to read. I bought the magazine on Ebay to get the article.

BTW, other top FE builders do this same modification. Of course, Brent isn't one of them.
I do not agree with Teds opening of the mains passages, to 5/16 to the main bearings. It gets to close to the edge of the cam bearings and is no benifit, because the annular grooves will only allow the capacity of the existing 1/4" hole but, if I had a way to increase the width annular grooves, to .281 and the depth, to .142, I would drill them to 9/32 (.281). But, remember, Ted ran his .050 over, 352 for years, drilled like that, at up to 8300 rpm launches and shifting at 7500 rpm and HP in the 450/500 range.
Enjoy, it's a great read and shows what the FE could do, "back in the old'n days".
Also, note that he used the C0AE heads and heavily modified the chambers. VHS was one of the top head porters, in those days.
I also think is very beneficial, to block the feed to the heads and run a separate lines, off the rear of the main oil gallery. That way you don't loose any oil to #2 & #4 main bearings.
While my engine doesn't really "need" these mods for the HP and rpm level it will have, I was able to do the fixtures and use them for my other 361 (indust) that will benefit from them.
