    Got a set of 308 heads to work on from a member here, he can chime in if he would like to reveal who he is.
    Job description..

    Port already machined set of 308 heads
    2.02/1.60 eddy valves,springs,locks
    Milled with a primitive valve job.

    I already know what I'm advising the customer, hard seats on both sides and another valve job. Have a look.

      The history on these heads is I took them in on a swap.

      Then gathered up the valves, retainers, springs and keepers from the edelbrock aluminum heads.

      Took them to Shots machine shop in galesberg to have the work done. After he has a heart attack and later falling off a 4 wheeler he called me they're done come pick them up.

      A year and a half he had them. He tells me what a wonderful job he did.
      I take them home in thick plastic bags and set them on a shelf.

      I talk to MO about doing a porting job on them. Finally ship them to him last week.

      My goal was a set of iron edelbrock equiped 308s that flowed good.
      Can they be saved, I hoping so.

                    Nothing is decided yet.
                    You have to have them in front of you, they sank the valves more than I've ever seen,
                    Other option is a serdi 5 angle cutter to make a better chamber side radius.

                    Shop sank the valves to use the eddy springs is my first guess. That hurts these heads and you lose potential. I would have bought another set of springs, not sunk the valves flush with the chamber....cause that's what we are talking about here.

                      They are sunk for sure @ 1.770" IH but what is the goal? 400HP-don't bother, 500 hp go for seats. That's a ton of work and only worth it if.....J.Rob

                        Yep, put a headstone over those fkrs, theyre buried!
                        Agreed, no need going broke if the goal hp doesn't match the dollar spent. Good thing is the seats I can do for a lot less than most, if absolutely needed. I know what I can do with the right seat height, that's the thing.
                        The goal with them is a fat low lift with about 255-260 cfm by .500 ..... the sunk valves aren't a great way to start chasing good low lift #' s.

                          They go on a .060 over 340 using TRW forged 10 or 10.50 stock replacement pistons. At present have a 508 Purple Stripe cam but want to go more lift later. Holley Strip dominator with 3310 carb.

                              When the final numbers are in... a cam will be recommended. I'm not building this motor , just making the heads worth their weight.
