Mast 305 heads?
Well i finally decided to go with Mast LS7 305 head for my twin build and have a question for anyone that may be running them will the Mast head have guide issues like the factory heads? They are going to have lightweight valves and i was planning on CHE or Trunion'd stock rockers cam will be mild lobed around .640 lift i guess the mast heads come with bronze guides not very specific in the listing?
