Build it clean and ALL oem, even the slug if you can, but meteor is ok.
Then send it to a builder and let them have there way with it. Porting/performance upgrade are a lot of work and take a lot of equipment. You’ll get a better result sending it out. I no longer port saws professionally myself-that’s over.
460’s have good factory compression. An oem piston is around 12 grams( not 100% on number) lighter than a meteor. Meteor has wider skirts than oem, so you can go wider on the ports with one.
Forget a popup, do a .025 chamber cut and lower the jug. You’ll be at around 190-200 psi, which is the sweet spot.
A stock 460 oiler should be fine with a 25. There is an HO oiler upgrade, the piston is easily identifiable as it has a groove in the gear that the standard one doesn’t.
Here’s an 8 pin 25
Here’s a 36” 7pin
