Big block 383 build!

Ok just to let people know it has been awhile but i pick up rotating assembley from hensleys in 2 weeks when income tax gets here!So gonna start putting motor back together but now need to ask another question!Got my 906 heads took apart and inspected them and found 1 head must have got water in it and looks like new guides and seats are gonna have to be put in!So my question is do i put out the money to fix 906's or should i buy 440 source stealth heads and what should be done to them out of box?Thanks for any replies!

Go with the 440 source heads or a set of Edelbrock RPM if you can scrape a little more money together.Either is money well spent over stock heads
