I've got a shed full of tools and machines and I can do everything accept cut a 45 degree valve seat in my ported 906 heads, I've tried all the local suppliers, the web, you name it and come up with nothing apart from very expensive sets, and I've already got a full set, apart from one this size!

Does anyone have a 45 degree valve seat cutter big enough to cut a seat for a 2.14" inlet valve, that I can beg, steal borrow, hire, buy or whatever?

HELP!!! :(

Surely it can't be just me that likes to build quick engines engines around here?
Or maybe I've logged into the M*x P*wer site? Can anyone help me with a set of neons and some subs then? :?

Ivor still looking as promised, can't catch up with my mate the agricultural engineer yet, but Paynes have just quoted ?25 per head + VAT

JonB, Is that price really per head or per valve?

I went to Paynes Thursday Kev, PROPER engineering shop and it is ?25 per head, which I thought was good value.

Anyway, I would like to do the seats in a certain way, so I have actually ordered a cutter to be custom made for the big valves...I'll let you know how I get on, but if it all goes wrong, Steve Ball has offered a back up solution.

Thanks guys! 8)

Ivor. Why are you not having three angle heads?

Kev, as Ivor confirms ?25 per head, they have jut done my rebore, micro polished the crank, pressed the new pistons onto the rods, cleaned the rods, and washed the whole assembly in their de grease bath for ?270.00 which I thought was a bargain.

Hope to take my axle to BJ Nostalgia for shortening in the next few weeks, so the plan is under way.

Good question Kev, I've done three angle and even five angle in the past, though personally, I don't think it made a blind it of difference!

Anyway, I've followed the MP templates as far as bowl shape is concerned and shaped the ports the way I've done a couple of Cossie heads in the past in the past and found that the two angle job works really well.

If I'm wrong and the Taxi takes me to the cleaners, I'll run the 60 degree cutter down there too!

I have to admit that when I port heads I shape (round) each side of the valve seat by hand. I make the 45 degree seat more narrow than stock but I cannot remember off-hand what seat width I have used.

Long time since I did one!
