More Magnum Block Oiling Questions
So do the later blocks without the oil holes NOT have those 1/2” cast tunnels in the valley? I’ve never taken the heads off my 5.9 to see if the oil holes are there, but it appears to have the cast tunnels (pic from several years ago). Speedmaster STILL doesn’t have their stainless rockers (oil through pushrod style) in stock. Could buy prw’s but they’re twice the price. If the oil holes are there, I can buy any LA rockers.
