Need new heads

[neal1980]

Looking at avilable heads to fit over the winter to get a bit more flow into the engine, what would be the verdict on these...

I would speak to Rob at V8D, personally i haven't heard of stage 6 heads unless they added a couple for the wills ring machining, also i'm sure someone will be along shortly to say you can get bigger valves in there too

They're basically like mine, but without the extra porting & flow benching from Peter. Most of the 430 BV's had the ringed heads ported to that spec, in fact if you can get some 430 std heads it should only cost @£500 to get them to that BV spec. Big problem with the ringed heads is that you are limited in gasket choice, otherwise its all upsides as long as you can bear the cost of copper

There is nothing really special about DJE's heads over decent 500 BV heads as far as I can tell, just the ringing and its easy enough to get the valve guides bulleted down without taking them out of the heads if they are the later humongous ones in the 500.. Whether 5/16 makes a great deal over 11/32 is arguable ~ I don't think it would worry you too much. Certainly Pete B would find it easy enough as they make their own valve guides anyway and I don't think 5/16 valves cost anymore than the std 11/32 ones (just a different retainer & collets maybe cosworth style IIRC).

Don't know about the heads but the supercharger kit @ 399 in the bottom left associated items listings selections looks cheaper than expected

which doesn't include the blower

The thing is how much power/torque would these heads give you,I've seen suggestions that the 4.3 B.V heads increase power by about 15bhp,which doesn't sound that much to me,but it does fit in with the £100/bhp figure,which people quote.

Pics of mine.

Same as Stage VI listed but no O-ringed as have been skimmed.
