Heads
Alright so my truck is burning oil. I think I have narrowed it down to valve seals. This is on a 302 in a 1970 F-100 by the way. But I have decided I'm going to go ahead and get a full valve job on the truck. I have found a shop that will do it for $199, and they said I can either have mine re-done or just do an exchange. Which would be the better way to go? I plan to also swap out my cam while the truck is apart so the turnaround time for re-doing mine is not a problem. I just wondered if anyone has an opinion as to which way would be the better route to go.
Also, I was looking through a re-build book I have and it says something about the being a code on the head that signifies it as a truck head. Does anyone know if there is a difference between these and other heads?
Thanks!

It's never a bad idea to have your own done. With exchange heads you don't know how many repairs have been done on the castings(crack repair, thread repair, etc..) or if they are a matched set.
If you are changing the cam you also need to install the correct valve springs for that cam.

The 302 is so easy to work on, I'd encourage you to pull heads yourself swap out cam for an RV type cam and new lifters, Use your own heads they probably don't have any issues. A word of caution: If you have to replace the seats and or a bunch of valves, you just might consider a new set of heads from WORLD PRODUCTS. If you need help you may contact me directly, I had a race car running a 289/302/ 4 speed top loader 9" rear for many years, I've already made all the mistakes. Bill Leland, used to live in Tucson

Yeah that's one of the reasons why i love my 302. I always used to work on my dad's cars and no I can enjoy working on my own. I'm only 18 so it's nice to have an easy engine when I'm sorta teachin myself (with a little help from my dad and all you great ppl at FTE here ). Plus you can get some good power on it while still staying in the double digits on gas mileage lol.
And as for the springs, I actually had to go in and replace the lifters, and saw a lifter/cam set on summit so I got that. Summit SUM-K3600 - Summit® Cam and Lifter Kits - summitracing.com That is the set, I haven't gone to look at the details yet but i think it was something like .450 lift on intake, .470 lift on exhaust and somewhere around 260 or 270 duration for both, I have seen some places saying I won't need different springs with it, is this correct or is it another case of ppl don't know what they're talking about?
And thanks Bill I will definitely keep your e-mail on file. Just a bit curious, where are you at now anyway? I'm in glendale myself.

RE: valve springs, If you aren't going to be redlining engine, I'm sure the genny parts will work just fine.
