westcoast dome chart thing?

[Mouthfulloflake]

so I got this 701 westcoast head, I KNOW a few years ago I saw a chart that showed the dome sizes, part numbers, and the compression they gave...

does any one know of that chart?

ive googled, and searched , and looked, and im coming up empty.

Thanks in advance.

Pro-Tec has a chart on their web site. I don't think you will find anything from Westcoast on the net.

I found this.

and that does sort of help, but im not sure how to translate this westcoast dome number into a CC number?

The westcoast head says right on the top of the dome. It should say 701 29 last 2 numbers are dome size. I dont know about that chart though i have 3westcoast heads I have 29cc domes in my blaster and with a 20 over bore I believe 81.5mm it makes between 180-195 psi cranking depending on gauge used. So even if their numbers are on a running motor I cant see it making 245psi just my $.02.

i have the 701 westcoast head on my blaster too with the 29cc domes, makes 180 i beleive.

I think these domes have 5051 as the last digits?

Ill have to look again I gues.

You probably have a wetjet head. My buddy has the same one that came off a wetjet kraze dont know what numbers are on his domes but his stock bore blaster makes 160psi.

it has a westcoast racing logo on it.

the number on the head is 9103 5050

the domes have 9103 5051 00

any ideas?

this is yamasluts old head by the way ( if that helps any)

What color is it? My buddys had th wc logo on it too. His was like a gold color. Unless it has been painted it should be blue or black and gold. Blue is standard model black and gold is race series, gold is wet jet hpe this helps.

Just CC the domes and you'll know for sure.

so... sparkplug in, head upside down, and fill it and measure?

or do I need some fancy plexiglass cover and pipettes, maybe a titration tube or some digital doser pump....

maybe I will just wait and measure it with a compression guage, but I was wanting to dial in some stator plate advance as well.....
