Well as many of you already know my 450 dropped a valve a couple weeks ago. I just put a new ported head on with a hc1 I bought used off a friend. We'll come to find out the cam was spun (retarded) causing the exhaust valves to hit the piston. Finally one snapped

So here is my plans:
-ported Baldwin head with +1 valves (it's to good of a deal to pass up)
-stock cylinder
-CP 12.5:1 Piston
-oem main crank bearings
-oem new crank
-oem gaskets
-943/921 Web Cam Or the stage 1 hotcam that destroyed everything (I got it degreed and welded)


Pics of the damage

I see that you have a stock case saver. Do yourself a favor, get a poly case saver! The one i have on now is by Moose Racing. El Mamito USMC hit the nail on its head perfect. Might as well do it all up while it's apart already. If you have little extra money, i'd get 2 cams. HRC and hot cam stage 2. So you can try both out and pick which you like the best. Some like hrc and some prefer hot cam.

I'm subscribing to this thread. Because your plans sounds pretty much similar to my future plan (spring time i hope). The only difference would be the head. Maybe it will be from matt at dynomite or OCP. What do you have now for sprockets? I went down one tooth on the front sprocket. Figured you might have done the same.

I've got that also on the list Bvet but this is just for mainly the engine. But it might take me a year go get everything done. But if I can get that head ported by Baldwin, it has +1 valves in it with less then 5 hrs on it.

There is a guy on fb that designs and makes his own chain sliders and case savers. His name is glann innovations. That's the ones I will be buying. Also I'm going with the drop in web or staying with my stage 1. I don't have the money to be buying and testing different parts.

ill say stay with the HC1. I heard web is really agressive on the valve train( again i dont have previous experience on this but other people that have they say the same)

im interested in a chain guide or slider.. post some pics... and links.. since i want a guide but i want to keep my PRM skid plate..

They build a couple that are drop and go. I was running a 493/729 when my valves dropped. John @ Racer's Edge says, they are very hard on the valve train.

943/921 web is a drop in cam. Similar to the stage 2
Save yourself some money and go with the stage 2. They are very close, to the same specs. Those Web's aren't cheap.

Here's the problem that caused everything. The two cut marks on the flange was lined up with the two marks on the cam. So that should tell you how off it was

get it degree'd and welded and run them both... that way you know which one you like better. you can always sell whichever you don't want to run.
