It this supposed to be 45mm intake valves?

 

Do you know what type valve seats are fitted and what angle job was done?

[Scoota G]

N42 should be 44MM me be thinking.

yep 44's ( my typo) and 38's in this one

3 angle cut, and later stellite steel seats so ok for unleaded.

I just run avgas in the race engines it gives me a cleaner slower burn rate, more consistent,  and the bit of lead helps soften impact of valve on seat.

 

my current P90 with 4mm shaved is running 47/38 valves, breathes real nice.

I'll take it. Me shall be in touch next week... Good luck on the weekend.

Scoota - more power. 

 

The library better watch out now, they are living dangerously being on the drift (roundabout) track.

[Scoota G]

And it's here. This means that i'll take mine off and then probably sell it, it's been ported by me but this one i just received is Ported, ported.

[furrybarry]

Anything modified on yours apart from the porting Scoota?

[Scoota G]

You mean the engine? It's got

Crow Cam

Genie Extractors

40 Thou Over

Hypertec Pistons

Chrome Moly Rings

Resized Rods

Fully Balanced

Electronic Ignition

Triple 45mm Dellortos

Cold Air Intake

Thats it i think apart from the 120 amp alternator the Aluminium Radiator. Just a reliable and strong Street motor i guess.

Dyno results?

When has your username been changed to Scoota G?

[Scoota G]

It hasn't been on the Dyno yet but it will this year. Yea i changed my user name because that was what it was supposed to be but i didn't know you could.

So this Head has been sent H&M in Melbourne and will cost about $250 to repair the hole which will come with a warranty too.
