summit and comp cams said yes.. .good to .480 :bow:
I'd double check myself.
Built a crate L31 for a friend and the valve seals hit the retainers around .460" of lift on some valves. Also, maybe wrong, but the heads need to be drilled for internal coolant bypass. When I set a old style head gasket on the new vortec heads there is a coolant bypass from the waterpump passage that is not drilled on the vortec heads. I drilled them out so I didn't have to run an external bypass from the waterpump to the intake.

We ran the GM "hot cam" kit in that motor. I has a .525/.525 roller cam with about 218/220 @.050 duration. Had to open up the spring pockets and machine down the stems for clearance, that was only $50 at the machine shop.
 
thanks for the bits of information... well seems im scrapping this entire idea....
getting a 1987 1 ton 4x4 complete with bbc 454... gonna drop the 454 and all wiring into my truck.. dont want tbi.. but hell might as well.. dont have to touch the carb or anything..... mild 454 will do me fine.... :wink1:

anyone need vortec heads? gonna list them in the f/s section.... $200 takes them.. i got them from a guy that said they have less than 100 miles....
