Is it ok to plug my dads company here?

I just wanted to let you know that if you have any head work that needs doing then my dads business can do it.
Its a small red building in a street just off Victoria Road, Fenton, Stoke-on-Trent buy the Foaming Tankard pub.

They do:
Pressure testing
Head Skimming

i forgot the rest lol
I'll get some more info when he gets back from work because i really cant remember.
If you've ever been to Yates and found their prices too high then my dads place is the place to go
He used to work at Brunts in Silverdale before he was made redundant. Him and his businss partner both have about 25-30 years experience each.
If you go in, Glynn, is my dad so say i sent you

Do they do head porting and polishing as well?

oooo.. i want some headwork doing..and live in staffs.

do they do porting/polishing?

I dont think he does that.....not sure.
Basically, they recondition cylinder heads, so if its knackered they can more than likely do it

oh, if he doesnt do porting and polishing, im sure he can recomend some place.

cool, my spare 'ead has only done around 30k so should be sweet still - might pop it into them to have a check over though. I've heard somewhere down in cannock are alreet too.. not sure who or where they are though.

you found out yet mate?

porting a head is fine.polishing is for idiots.it stops the droplets from moving through the port.you should have a roughish finish for power.

He says he doesnt do porting and polishing but he says its pretty easy to do yourself. Alls you need is a wire brush. (He uses one attached to a air powered drill sort of thing. Works a treat)

Anyway, how is polishing for idiots? And how would roughage make more power?

The idea is to make the flow as smooth as possible. That means less contact with the sides so the fuel goes in faster

not true, turbulant air is good as well.

cheers

fancy asking him how much to skim a head, and also regrind all the valves (only 8) - generally check it over

Prices Please!!!!

And More Info

Thanks

It doesnt make power, it promotes swirl, which in turn means better combustion as the fuel is better spread around the air charge

On the exhaust side that much is true. But even on a polished surface, there will be some skin friction and associated drag because its impossible to get a perfectly smooth surface. But the speed of air flow in is limited by the area it can flow through more than anything....the friction isnt THAT much of an issue.....

The ideal thing to do with inlet ports is open them up and get a uniformly surface finish (eg: as near as cast as possible), then matching the manifold for size,shape and roughness.

With exhausts, yes...polish that by all means, but DONT match the port sizes. Enlarging them is fair enough, but exhaust port matching is a definate no-no

This is definitively not the way to do porting. There is quite a bit more to it. Additionally the head should be flowed to make sure that you have an even flow rate. While you are porting you want to maintain a slight taper and porting round the valve stem guide is a pretty skilled job if you want to get it right as it is around the valve seat.

While this is done it makes sense to give the valve seats a multi angle cut.

And what arseofbox mentioned is essential for each side as he described.

BTW if forum members are interested the 8v FIRE heads can be ported and flowed for about £200 (including any sort of skimming). Pressure test is extra.

do members on here get discounts?

This is alredy discounted. What are you after?

Ahhh may have to pop round, i usually go yates, cant grumble at there prices really, but if your cheaper...well.....even better

I know that this is an old thread, but I think my question is relavent...

My understanding of port matching is to take the manifold, the gasket & the block & enlarge the openings until they match up?

Again I think I'm reaching the limits of my understanding - Why would exhaust port MATCHING be a bad thing vs ENLARGING?

My only guess is that by matching you mean opening up the port further into the block than just matching sizes up at the entrance

Reason I ask is that my 1108 Mpi Sei is due to have a Supersprint manifold put onto it & when I compared the manifold to my spare scrap P75 head (which I believe has similar sized ports?) the 4 S/S manifold branches will need a gasket far more circular & wide than the ports in the P75 head. At the moment this difference will leave a distinct lip
