nackerd cylinder head (free ?)

any one got a nackerd head off any kind but preferably an sv head

i want to have a go at porting/flowing a head, as i have to do one at collage but we dont have enough time to spend perfecting it so wanted to do a bit at home.

any one willing to donate a head thats shot, not wanted or other wise ?

will pay P&P as long as its not to much

Sure.. postage might be a couple of quid though as they're pretty heavy

what you got then YC ?

A front head from curvy that a collet jumped out of... the valve didn't drop so it's not FUBAR but I wouldn't want to use it... be fine just for looking how far you can go on ports without breaking into waterways or whatever. As far as I know they didn't make massive changes to 2gen until they went to twin spark

cool, if you could find out how much P&P is ill have it

P.S back in day when I was playing with considerable vibration and harshness engine we found taking too much out of ports just made it peaky, got lots more torque with just smoothing rather than a massive port. Actually made more power with sport cam too rather than the mad one kent (iirc) made.

I don't think you can do it just on flowbench for best results... you need lots of dyno time. I could use CFD and get lovely smooth flow everywhere... and it would probably run like bag of crap... big trade offs between flow, mixing, velocity etc

ok cheers we will be going through all of this soon on one of the cars we are working on as a few of them have to have the head's replaced, as they have a shelf life on race cars (most are post 95 cars), and the cars are going to be run(tracked) again this year for the first time in about 10 years
