Thanks Man!!! When I received these heads they was terrible! Just for you have any idea, springs locator was pasted with 3M glue, valve guides with excessive clearance, poor valve job, valve spring install height wrong... Terror movie!!!

Look at the picture and you will see spring locator was pasted!
