Sorry about all the posts on this subject but I don't know that much about it and I feel it is a critical component to my "cheap" 302 buildup. I have a line on some D0OE heads that have:
A valve job
New springs
New guides (no guide plates)
Screw in studs
Bumps clogging exhaust removed
2000 miles on them
For $250. How high RPM will stock springs not float at? I'm looking for 6000. He said he had them to 5700. Are guide plates necessary for solid lifters? What are guide plates anyway? If the springs will work and I don't need guide plates all I need for these heads are hardened valve seats. What do you think?
Thanks. ------------------

The springs and all settings dealing with the springs are connected to what cam you are using. You need to be sure that the spings you are going to use are the correct ones for the cam. As for guide plates yes, you need them. If you are looking to save a couple of bucks- I would skip the hardened valve seats. They will cost you quite a few bucks plus I (nor many others) am not convinced they are really that necessary. I am sure someone will give more info on that.later

BUY THE HEADS Sprcoop! That is a good deal.  You can install the guide plates yourself, but you can also live without them. I would pull a spring off and check the seat pressure. It needs to be at least 100 lbs. with the 270S cam. You can probably shim them to that.  Alex------------------

Thanks Chip and Alex,
I need no further recommendation than that of the Master (is that sucking up?). Hey, you didn't just say that because you're sick and tired of me posting questions about this now did you? Just kidding, it sounded like a pretty smokin deal to me also. I just emailed him that it was a go. Chip, I talked to a machine shop today and the guy said if it was him he would save the $125 and run the heads without the hardened valve seats. He said he has done hundreds of older heads without putting in hardened valve seats and not one has come back with a problem yet. I figure that is a pretty good recommendation since he was looking to make some money and all I did was ask him how much it would cost. I think he needs a business coach...or maybe he gets business because of his honesty? Hmmmm... I'm still wondering what exactly guide plates are? That's a new term for me (most of them are). Thanks again for your help. ------------------

Guideplates install under the rocker arm studs and keep the pushrod aligned so it makes good contact with the rocker arm. checkout the online catalog at summitracing.com in the valvetrain section (or maybe cam accessories) you will find guideplates, they have pictures of them.------------------
