whats the casting numbers on the heads, you can usually find out what the CC is on chevy heads, or are you gonna mill 'em :) Ebay has some cheap stuff that might do the trick for at home work

Hi 74, I was able to c.c. mine with very little cash outlay. I used a 60 c.c. plastic syringe ( wife is in medical field ), bought a piece of 1/2 in. clear acrylic plate for $3.00, drilled the plate so I could bolt it to the head through the head bolt holes and presto - one c.c. kit. I started out wanting to c.c. mine just to determine the compression ratio before I put the motor together, I found a two c.c. difference between the heads, both have the same casting # but one is a 1971 and the other a 1972. Some of the books I have also said that GM was still changing the head volume between years to meet emissions. So a little milling on the 76 c.c. head brought it down to 74 c.c. to match the other. I used water as the measuring fluid, you will want to measure more than once to get a good feel for the accuracy. You can use a light oil like tranny fluid but things tend to get messy.

Did the same thing with a friend's 427. Also used water w/ a little food coloring to make it easier to see as it filled up. Only difference was we used a piece of plastic that just covered one combustion chamber and sealed it to the head with a light film of grease. Probably not as accurate as yours but we were just looking to get a rough idea of CR.

Somebody once said "Necessity is the mother of invention" :)

Thanks for the info guys. I have done a little hunting around on the internet and i found this kit http://www.precisionmeasure.com/block15.htm
Has anyone ever heard of Percision Measuring? Any feedback on them or the kit?

I'm too cheap to spend that kinda' money on something I may never use again, if your going to be doing a lot of head work then it would be justified, it all depends on how much your willing to spend and what end result your after. For me I achieved exactly what I set out to do with a couple of dollars and a little time.

I agree w/ 78buckshot . About the only difference I can see between the way we did it and that rig is probably a little accuracy. And oh yeah, $150.
