Oh shit nigger
Is that the intake?
Dont polish an intake you fart sniffer

You should stop and figure out what you're going to do first.

>>16316690
It's not polished and I don't plan on polishing it

Ok what about port/gasket matching?

Here's another one

I'm aware it's probably going to do nothing, I'm just doing it because I have the head off because I'm doing a the head gasket

>>16316713
port/gasket matching is good but look into what you can port farther down. if you only widen the outside you will set it up to make power at the upper end of your rpms.

>>16316722
Grinding on the intake wont do anything other than make you get poor mpg with no gain.

>>16316684
take the valves out

>>16317011
Yeah I should do that huh. I don't have the tool

Best gains will be from blending in the machining marks made when the valve seat was fitted and the seat angles were cut.

Thanks man

>hey guyz, i hav no idea wot im doin LOL plz help me PORT MY FUCKING CYLINDER HEAD

jesus fuck
just put it back, anon

Ok here's the story

My friend doesn't really know what hes doing and he had me over today and showed me his port job. Just trying to figure out how to salvage this basically.

>>16317374
You can't. You'll only fuck it up more messing with it. Put it back as is and pray the fucking thing still works.

>>16317398
>still works

ok this is how I know you don't know what you're talking about

Tfw you port matched your 302. Put a bigger cam in it. Get a bigger carb. Then gain 100hp.

I wish cars were that simple still. But l did grab 1500 extra rpm so hp was easy.

>>16316684
Its best to start with a fully disassembled head...
Google pocket port.
???
Profit

>>16317468
port matching didnt give that kind of increase. The Cam/carb combo did.

>>16317499
Oh l know. Its just. Life was simpler back then. The only reason lve actually kept the car. Old single cam cars are so easy to fuck with.
I know the mustang has gained 3 cams and 210hp since the fox, but l sure do miss opening my engine bay and honestly knowing what l could do and never risk a code or limp mode.

>>16318062
>swaping cams
>complicated
OH NO THERES TWO CAMS

I CANT DEAL WITH TWO.

MY BLEEDING ANUS.

yeah nah fuck off cunt. Swapping in a bigger cam is not hard even on a post 2k engine.

So long as you buy the right ohm and diameter injectors swapping those is not hard but most of the time you dont even need to do that just throw the car on a dyno and get the ECU tuned, WHICH IS A MILLION TIMES EASIER THAN JETTING A CARB.

Especially if youre running more than one carb, holy fuck.

>>16318172
>WHICH IS A MILLION TIMES EASIER THAN JETTING A CARB
Not really, especially if you have a wideband. EFI is pretty easy, but costs a lot of money. A new high performance intake and a used carb with a rebuild kit will net you as much horsepower as port fuel injection can at the top end

The big benefit to EFI is everything under the curve and cold starts

>>16316684
Disassemble the head. By leaving it together you open up the chance for metal shavings to become lodged in the head. These can cause damage once reinstalled.

Since you don't know what your doing regarding match a port job so a set of cams, springs and valves etc. And your probably keeping the motor stock I'd recommended just port matching the intake manifold and cylinder head to the gasket. It will give slightly better flow and work well with the factory camshafts.

A spring compressor tool can be had for $20 off of eBay. Make sure you get the one meant for overhead cams, not over head valves.
