ok so spent yesterday afternoon and this afternoon dismantling the head and cleaning, the valve springs came off quite easily and had no major
problems apart from a collet flying away somewhere that took me ages to find. the valves on the other hand were in a bit of a state and some
mega-cleaning was needed to get them back into shape (this was most of my day!)
 
as you can see the head was pretty manky and covered in crud! but after a bit of cleaning it came up alright
 
here are the valve ports, i have only just started working on these the seats don't appear to be in too bad a shape either, i was quite
surprised. the cam is in good knick aswell, no scroring on the lobes at all.
 
the photo doesn't really show the extent of how bad the valves were, especially the exhaust valves (inlet pictured on left), you can probably
see in the top photo, the exhaust valves that is. i have had to order some new valve stem seals because they were absolutely knackered! pretty much
ripped to pieces.
tomorrow im hoping to get the head finished and painted, i might even have a little go at some light porting of the inlets, and then get the head and
rest of the bits and pieces painted.
will keep you posted

Fantastic pictures and article.
I have been informed that my 4th cyclinder valve stem seals need replacing and have intending to do all of them but was reluctant to take the head
off.
But seeing the picures and thinking what else I could do I may give it a go......
Keep up the good work....

This is my next major stage of the build (1.6 Pinto) so watching this article with interest
Looking good, just hope my cam is in good nick too! Think I'll be taking lots of piccies throughout.

You can change Pinto valve stem seals in situ....
I did mine a week before SVA and only one collet flew across the garage!

pinto recon continues: Porting the head
carrying on with my pinto rebuild today, i did a bit of porting on the head, took me pretty much all day to do as the exhaust ports were a right mess,
pictures below, i managed to polish up the valves as well

that must be hard going being cast iron head.
make sure you lay the gaskets on top to open out the inlet and exhaust ports to match.
I used a 1/2 round hand file and dremel stones but the don't last long. To finish off I use a small sanding wheel followed by 180 wet
'n' dry.

looking good...
you could loose some material from the valve guides in to allow a little more flow...
I had a document somewhere detailing how much material you can safely remove from a Pinto head that i used when porting mine.... you can take loads
off the exhaust ports but general consensus is that the inlets are pretty big already and just need fettling.....
Basically got some over sized cometic exhaust gaskets and opened the ports to to match

i have removed some of the material from around the guides and removed all sharpe edges so they are all nice and rounded, the only problem with
removing valve guide material is that it reduces the longevity of the head and since im not having brass guides fitted im not going to remove a great
deal.

I figured that if the engine only lasts 20k thats probably a lot longer than I need so hacked away loads! my inlet guides now are just a small
smooth bump!

yep - you don't get something for nothing.
that may be an issue for a 10,000 mile commuter but we do lower mileages in aour kits and swap/rebuild engines out all the time!
NB going to bigger gaskets would need you need to open the inlet and exhasut manifolds out - the exaust may not be possible.

On a Pinto head you can take loads off the exhaust ports

its been a while since i have posted an update on my pintorebuild but thats because i haven't been doing much lately, due to other
commitments,
but last night i managed to get in to the garage and rebuild the head, i've reseated all the valves, new stem seals, new cam seal, new oil spray
bar. cam & followers are in very good condition with hardly any wear on them at all, here area few shots of the head being rebuilt. i managed to
get a lick of paint on the head too and the cam pulley and backplate as well.
     
   
i know some of you guys were watching the progress of the rebuild so my apologies for the delay in posting,
im off to set the valve clearences now.
All the best
Alex

your at the same stage as me now....

have you got that spare head ported yet ?

When I looked at this thread last night, there was a big picture that meant I had to keep scanning across.
This morning, unless I dreamt it, it was gone and a series of pictures that fitted into the standard frame had taken their place.
Now the big pic is back
Did I dream it?

ps edit, nothing about editing in the post in question, must be the way it's displaying

Sump Cleaning URGH!
over the weekend and for today i went on the dirty adventure of cleaning the sump! it was aweful! the inside was fairly clean to be fair but the
outside was rusted beyond belief! it took 24 hrs in the electroysis bin and a couple of hours on the bench drill to get it looking half decent.
i managed to get it primed up today and will paint it tomorrow.
after elctrolysis and wire brush
  
first layer of primer!
 
2nd coat of primer
 
will post painted sump pictures tomorrow.!

That doesn't look too bad at all - most of mine had holes in them
