| RE: head question |

I am using a set of EDCE's with machined chambers on my 390. Since they have taller intake ports that match my dual quad lowriser intake I decided to mill them because they had larger chambers than my GT heads which would have lowered my compression. So They were cut down to 68 cc's . Combined with larger valves and my .040 overbore 0 deck and L2290 pistons the comporession works out to aprox 11:1. I still have the ariginal heads fresh just in case. My engine is still in my running engine stand and being tested. no other specs yet but i think it must be a boost in hp torque etc...
