First one too, I’m well pleased seeing it with a finished look, got more digging to do to get uniform but overall looks A one to me.
I’m now collecting the ruddy things, incl my own I have 4 in total biggrin

I’m gagging to pull these heads apart too.

I think I’ll go borrow some tools off a mate tomorrow if I get time thumbup

I read stuff about this years ago on here but understood little of it.

It’s only when you want to do something do you take any of it in.
Yella Terra
The pedestal ends spread the weight over a larger area and stop the risk of the rocker shafts rocking on their small mounts.

The washers or shims inbetween each sexy aero grade rocker are bespoke so you measure and fit them to suit so you get Perfect centreing of rocker over each valve.
Red hot is what they are if expensive.
I have no idea what I’m doing other than listening to other people and doing what is the norm for any 5.0 set of heads really.

I’d really like to take a look at some 5.0 heads before long too. Dom might have an old one I can measure up smile

Adjustable rods are OK but are very fiddly to get right. They are a real compromise. A better solution is an adjustable roller rocker. They are only really needed with solid lifter cams.

Modern cars have overheads cams. So, no real relation to these engines.

Roller cams are the way forward for us.. but they are expensive compared to a conventional cam but the performance gain is impressive.

Roller cams do look nice promoting high lift as they handle ramped up cam lobes better than flat lifters.

If you want the most aggressive cam then Roller Cam and followers might be a good buy as conventional high lift cams don’t last long anyway if subjected to much road driving. scratchchin

You’ve got to love PH
Starts out as a scratch of an inlet manifold and actually I only started this so I could have a cool looking fuel rail biggrin
So far the shopping list extends to full blown ported heads and manifold
Act big bore manifolds !!!
Yella Yerra rocker system
Now Roller cam added to the list.
If you could make up the perfect shopping list these things would surely be on it wink

Keep the ideas coming yes

That’s my plan anyway, not sure thats his yet wink

It won’t do Dom the slightest harm to be seen to be helping out those without well-filled wallets. Glad to see they are spreading a little human kindness and happiness.

The way I look at it there’s no free lunches and I’ll do some work for Dom to pay for it.
As he’s based in a city people often walk in off the street and he’s always doing things for people that we all never really get to see.
Less fortunate, I did spend 20k there over the years but yes he’s being very kind.
He’s so busy but the lads are really cool there and point me in the right direction.

That’s the Alun I know, always wanting to to be at least fair and pay his way.

My mower is working again. I took it into the local repair place earlier in the week, not starting. Knew it was fuel related, as it had a dry spark plug despite it having fuel and me cranking it like a whirling dervish. Bloke said “4 weeks mate, not surprisingly I am overrun with mowers right now”.

He called me yesterday to say it was fixed. Blow me down with a gnats backfire.....
Turned out the carburettor was flooded, and petrol mowers don’t run on water. Somebody must have left it out in a thunderstorm. Not that I am blaming my son in law.......

Water in the mix ain’t good.

Charge his account biggrin !

Thing is there’s got to be 10 people at least employed at Doms garage, that’s a big wage bill every week.
All I can say if he jacked in thousands of owners would be worse off.
He’s not expensive either when you look into it.
Parts are a bit steep at times but I know the lengths they go to to approve parts that actually work, I’ve seen Andy show some stuff he can get as suppliers are scarce and Dom reject them saying they’ll be coming back fked in know time yet others are happily selling the same stuff!

The rebuilt 4.0 engine Chim running Mbe today, should have heard how sweet and quiet the engine was.
You can’t help but be impressed.
Them there’s the Cerb that came as a bag of bits and someone’s got to work out what they all are. Carpet pieces etc. Not easy when you didn’t take it apart.
Big challenges as Matt will know.

Anyway now I’ve found the cleaning machine im putting an ad in the papers for perfect engine part cleaning services,,, Dom can charge me then hehe

Last few pics of a standard late head with intermediate sized valves.
These are as as good as it gets for Rover heads as standard I believe.

It was mentioned to me that knobby who works at Powers did all the porting and polishing back in the day on these heads so I’ve now decided it’s to easy to wreck them with one wrong move ( it’s highly skilled stuff welding cutting tools! )
I’m going to twist his arm ( bribe him ) into giving me some lessons.
I’ll hopefully do a few for Dom to pay for it sometime when I’ve proved my worth thumbup

At some point I must have dragged the head across something, use your brains when handling these especially face down ffs.

Haha,, smile

There’s no chance of that is there he’s the undisputed king, I just follow his lead,,,, guitar hehe

Guides seem really good as do valves/seats
The black baked on oil suggests low oil and or never changing the stuff as valve and plug colour suggested the vehicle they came off ran fine.


Here’s what the end product should look like which is the whole point of it laugh
