Thanks,
Then the noise trouble will be only with the lifters..

However,the last week i received a reply from Hughes:

Jorge,

Your compression ratio is extremely low for aluminum heads. Normally I don’t sell cams for an engine with low compression. We now have our Whiplash cams for low compression engines. They have very good low end and mid-range power, very aggressive idle characteristics, vacuum about 9”-11”. Cam P/N HMC3245BL ? Lifters P/N 5001,Springs P/N 1106. Check the cams out on our web site.

Thanks

What i did then was to took my time and measure the deck again ,using feeler gauges an a dial indicator with a magnetic base.(I was using a vernier caliper,wich is not so accurate).
I noticed that the deck distances went from 0.074" in the 1&2 cyls to
0.068 and 0.065 in other cylinders.
Then the comp .ratio will be more around 9.30:1 with a 0.039" gasket.
Using a 0.020" gasket it could go between 9.65-9.70:1.

I have sent another mail to hughes just for asking them if that cam could be still correct for this engine.

thanks again for any input
