Default Re: Milled heads and intake alignment

i have heads milled .055 and no intake alignment issues...some with .030, however, have alignment issues...


...these are not serious, however...to solve this problem remove the four metal alignment pins from the plastic intake and shave some metal off the diameter and length...use a file, sandpaper or whatever....

reinstall the pins and it should aling...you will know if you have a problem if the long intake bolts don't line up with the threads in the heads...
