460 question
does the 93 and later model 460s have bigger valves than the 88-92 models?
if so i was also wondering if i could put those heads on my 1991 460 without any problems?
and i was also wondering if their were any other performance differences between those year 460s? thanks

okay the only reason that i was wondering is because of an ebay listing that stated this....
"This is a complete 460 ci. engine. It was pulled from a wrecked 1994 F350 crew cab with unknown mileage. This motor was running great when the truck was wrecked. Since then it has been sitting for about 18 months. The wiring harness was taken previously, so I cound not start it before I pulled it out. It is not locked up and does turn over freely, but is sold as is. This engine does have the big valve EFI heads that the 88-92 models didn't."

Justin, nice truck in sig. I see you go to Silver Lake. You still have the banshee. I have 250r that I drag at the dunes. Only got out there once this past summer.
Maybe I'll see you out there next summer.

yeah they changed, 1992 heads had intake valves that measured 2.08, Ford used those valves until 87 and then went to 1.98, probably for emissions or MPG, then back to 2.08 in 93. i don't know if the heads are interchangable but i want to say they are the motor never really changed extremely.
