Pulled the heads off the '74 to lap the valves.
Used the vw tool to remove the retainers, but the valves won't fit down through the guides.
It seems the top of the stem is mushroomed slightly.
So its beyond my ability now.
Would like to get the guides and valves replaced.
Plenty of meat left on the seats.
Don't mind shipping if nobody local is worthy.
Any recommendations? _________________ '72 914 1.7

Any machine shop ought to be able to replace/grind/lap valves, springs, retainers, keepers and replace guides for you. You can lap the heads to the cylinders yourself.
If you're wanting performance work done, you might do well to farm that out to.one of the many vw specialty shops in California or something.
I got my head work done by a guy I made friends with, an older guy in a wheelchair who has built many race engines, and I basically paid him in vodka.
I'd recommend someone like this, lol. (He's in a nursing home now, though) _________________ "A poor workman always blames his parts... Ya gotta have skillz to hang junk." -johnnypan |

Thanks chief.
I wouldn't mind having the ports slightly worked.
Lots of casting slag in them. _________________ '72 914 1.7

If you have the time, and a little bit of money, I'd just order new everything, and use this as a chance to learn about head work. I worked with the old guy to do my heads, to the point that his contribution was mostly the shop to do the work in, and the knowledge for some really extensive port work. If you just want to clean them up a bit and maybe hog out the ports to match your gaskets, you can do it like he did mine, with a burr tool on a die grinder.
If you get new valves, you can just cut the tops off the old ones and slide them out.
To get the old guides out, we used an old valve with a steel sleeve on it as a punch, and after heating the head with a torch, hammered them out and the new ones in.
None of this is very hard, it just takes time... _________________ "A poor workman always blames his parts... Ya gotta have skillz to hang junk." -johnnypan |

Quick pricing shows about $100 per head for new ss valves and bronze guides.
Plus some labor to get the old heads usable.
Or about $500 for new heads with all new everything.
So for about $300 additional I can get all new heads and hardware ready to go?
Seems like a no brainer. _________________ '72 914 1.7

New heads won't be original VW stuff, though, for whatever significance that may have for you.
If your going to spend that kind of money, it mi6ghtbe worth looking into some Mexican heads with bigger valves. Those can usually be had for around $350, and usually are in good shape even used. _________________ "A poor workman always blames his parts... Ya gotta have skillz to hang junk." -johnnypan |

^X2 on the lash caps. I run them with sweeper style ratio rockers, and my valvetrain is quiet and smooth sounding with chromoly pushrods set @ loose zero. _________________ "A poor workman always blames his parts... Ya gotta have skillz to hang junk." -johnnypan |

I saw those.
Apparently mushrooming is pretty common?
And I thought I was special.
So much for a quick refresh!
With 6% leakdown I was hoping for a quick lapping and vroom vroom.
The valves felt good in the guides.
Now I will cut them off and replace with ss with the hardened caps.
And have one guide replaced.
Will new valves slip right in or will they need an angle job?
The valve seats have plenty of meat left on them.
Will these caps effect the pushrod required length?
Thanks guys! _________________ '72 914 1.7

New valves should be pretty close, but they will need to be lapped in with your seals.
Get one of those suction cup deals and some liquid sandpaper and spin away!
I'd recommend new springs, heavy duty ones if you want to rev high without floating valves.
You can mark the seats with something like Dykem and then lap to see if you like the seal pattern, or if you want to grind for more surface area or smoother flow.
If you're staying stock with the motor, and don't plant to run it hard, I'd get stock springs, and just lap new valves with the liquid sandpaper.
To accommodate the thickness of the lash caps, you can get away with spacing your rockers out with stainless steel washers under the blocks on the pedestal studs.
Stainless washers are thinner, so you have more control over how much spacing you want. _________________ "A poor workman always blames his parts... Ya gotta have skillz to hang junk." -johnnypan |
