So the new motor I got that was supposed to be ready to go isnt so much. Since now Im going to have to rebuild the whole thing, what heads should I use?? The #1 heads are off of the motor that I got and the #4's are on my original 330.. Meaning they need a valve job hardened seats etc..??

I havent found any info on either of these heads..

Thanks

Andy, check the wiki section on this site to see if they have the same volume of chambers. The #1 has the shaft for the rockers, that was an one year setup. The #4 has the more common aluminum bridges and rockers in pairs. I'd lean toward the #4's for that reason. My 2 cents. John
