Good Compression Number sor 9.0:1?

[93RiceKillinGT]

Hi guys
I did a compression test the other day and found the numbers to be between 147-150 PSI across all 8 cylinders. Is this a good reading for an engine putting out 9.0:1 compression with Gt40 y303 heads (63CC), and a camm with 10* over overlap, .533/.544 lift with 215/220 Degrees of duration?

My compression with the same heads as you was 145 -155 with the stock cam The car had 97000 miles on it.After the rebuild with the XE258 cam the compression is now 170 to 180.Part of the increase is probably due to putting in higher compression pistons and they were .030 over which raised my static compression to about 9.4 or 9.5.
