Changing heads
« on: March 03, 2013 - 08:14:35 AM »
I had planned on rebuilding the 440 over the winter, but it didn't happen. Is it ok to stick new heads on the 15 yr old rebuild or should I leave them on the shelf until I do the rebuild?  :dunno:

Firstly 15 years means nothing , my car has had maybe 200 miles in 15 years LOL
 you really have nothing to lose by putting the heads on , if the short block is weak it may burn some oil if the rings are weak . Is the head swap an upgrade to a better head ?  If they are alum heads I would use a cometic mls gasket

I hear ya. In 15 years I probably have less than 10k on it.
440 stealth heads. Heads on it now are I think if I remember, 452's. It is a 76 engine. The main reason the rebuild didn't go ahead was me dragging my a$$ aquiring a forged crank/short block with a forged crank.
