should fit round port, just dont hook up the pcv, the a10's just vented to the ground anyway

its the same bolt pattern the inner exhaust ports are a little close to the bridge in the manifold so my extractors will be a little different.

A14 Round port heads have a different bolt pattern on the intake manifold than standard A10 A12 round port heads. You may have just any old A12 round port head on the A14, best get those valve sizes increased.

A12 ROund




A14 Round

hmmmmmm sneaky sneaky so i have an a12 round port head on my a14 block i honestly dont know where to go from here.

a can of worms has been opened

Well you need to take some pictures of what you're talking about so we can offer some feedback with some certainty. The valve size is no major issue though.

Just run the gear and save up for the next upgrade.

haha il start a project thread tomorow night after work

Quote:There's a good reason why PCV systems have been made a legal requirement & another good reason why it's a good idea anyway.

Back in the 'good ol' days' when nobody could even spell PCV, engines would build up pollutants in the oil, such as water [a by product of combustion] & sulphur which is a component of the crude oil from which petrol is made. These two combine to form a mild sulphuric acid which doesn't do bearings or pistons much good.
Crankcase sludge was also a big problem.

Engine service life was 100,000 miles [160,000k] ....... if you were lucky.
With a PCV system & modern oils engine life can be three times this figure & crankcase sludge is a thing of the past.

When draught tube crankcase ventilation was the only thing around a great deal of oil in the form of micro droplets. This oil was sucked into the road surface when the weather was dry, but with a light fall of rain [drizzle was the worse] the oil would float to the surface & form what was widely known as 'summer ice' & it was responsible for far more vechicle accidents, injuries & even deaths that should ever have occured.

This, along with pollution control reasons, is why the PCV ststem is a legal requirement.

Stay clean, & stay legal, stay smart & use a PCV system.
