Slant six head
Did you use valve guides if so what material because i see iron valve guides for sale on rock auto but i have seen people talk about bronze valve guides being the way to go.
I don't know if they had to replace the guides in that head. I had told the machine shop to do so, if necessary. They didn't say anything about it either way. Though when I took this head in, I already had my OS valves and brought them in with it. Mine was a "whenever they get to it" back burner job. which I was OK with. But I also brought them a sheet that I typed up and printed off the computer (cuz I even sometimes have trouble reading my own scratch and scrawl) telling them some things I wanted done "no matter what" to that head.
I stopped by periodically, and we called back n forth with updates along the way, and every time they said they had "this part" done, I asked if they did something along the way that would involve "that part" of the job. and each time they acted surprised that I wanted what I was asking if they had done; things like.... I brought in oversized valves, it goes without saying that they would have to make the seats bigger, to accomodate..... which was a good thing because of all of my "slips" with the die grinder I had toasted a few of the original seats. But when I reminded them that I wanted hardened seats put in-- at least on the exhausts--- they came back with "we have the seats cut, they'll be fine" I said; "No, I want hardened seats cut out for, and pressed into this head". They resisted (because it meant a little bit of a back track) but finally agreed to do as I asked.
same thing happened again, when I asked if they'd cut down the tops of the guides, because I put in a larger than stock cam, and I didn't want the bottoms of the retainers to crash.
I don't know if they cut in a single angle seat, or a 3 angle seat. I do know, that they finished my start to a porting job/ and they magnafluxed it when done, to be sure that nobody "hit water" while porting..... neither I did or they did.... and that came up good.
when all was done I know I didn't get a printed out reciept that itemized what they did do.... just told me how much cash to bring them and they wrote me a "cash reciept" out of a generic reciept book that I think can even be bought at places like Walmart....
and the goofy part? that sheet that I handed them when I brought them the head was sitting right there on the bench right next to where they had been working on it when I picked the head up.
I have used these guys before, and I have never had a problem with anything they have done for me, prior to the machine work on this head/ and everything that I measured out to "check their work" on the block portion of this project, while I was assembling it, came out great. and they did go to extra measures to make sure that a questionable "line" on the block we both questioned, was a casting mark/flaw and not a crack.. they sent it out to be sonic tested and shot blasted over and above what I had asked them to do. I did the block and head as 2 seperate deals, one right after the other.
