Unless I'm missing something, with regards to the valves that have carbon on them, there are plenty of chemicals out there that will dissolve carbon so that you don't have to spend time cleaning them. Something such as Berryman's Chem Dip comes to mind.
If you really want to be cheap, you could do something such as taking a Mason jar, pour something such as B-12 Chemtool in it and put the valve in it and let it soak. That should dissolve the carbon right off. Just make sure you are taking precaution to cover your hands.
That might cost you $5 or so to do. Am I missing something?
I had given them a go with carburetor cleaner - I will try with something stronger before giving up
First attempt at lapping valves this weekend. Pretty pleased with how they turned out but wondering if I should go a couple more rounds with a finer compound to get more of a polished look. The valves seem to sit fine and I can spin them in their seats without resistance.
Doing this and watching porting and polishing videos makes me want to brake out the dremel and go to town on these things but I don't really know if I am that committed yet.
Don't overthink it. as long as they're smooth, clean mating surfaces that will make a good seal when closed, you're good to go.
Yeah I agree. I could easily see myself spending 30+ more hours on these things making them look pretty...and it won't make much/any difference in my application. New springs and keepers are en route, and that will be that. Any suggestions for (1) valve guide lubricant, if any, and (2) type of grease to hold the keepers in place during spring install?
Next phase is to figure out which headers will work.
I see you're in Plano. I've got a set of P heads I can bring you next week, I'm in Dallas weekly. PM if interested.
I may be interested depending upon condition & price. I have a pair of gt40p's and a single NIB GT40 head in the garage along with the supporting intakes. These are earmarked for the stang so I wouldn't mind having another pair for the truck, it could use a little more pep.. I'll send a PM.
Old thread, But BLDTruth, how did the build go? I’m new to the site, just payed my subscription fee. I noticed we’re in the same town, and I just picked up a set of GT40P heads for my 93 F150, with 5.0.
I found this thread while looking for info on headers to use.
so, did you use the GT40P heads, stay with stock cam, go with 1.7 rockers, what headers did you use?
