Re: oval heads for 502 crate/ 502 oil consumption
Wow 2007's still burn oil???
The 100cc Eddy's will actually bump the compression almost 2 points, as the iron heads are like 119cc. Eddy's have the new "E-street" head which is a little cheaper, like 1800.00 for the set. You will also need new heads bolts. If funds are available, the Brodix Race Rites are even better and will make more power than the Eddy's. Cam wise, I like the specs on that for a nice street 502. A cam with a little more lift would be even better like the Lunati 60622 231/239 .600 110lsa.
As far as oil burn, that's a tough one. If its from the rings, you may want to have the motor torn down, plate hone, and new ring set. That's what I had to do with my 454HO.
