Edelbrock heads.

That's exactly what I did when the Edelbrock head was pretty new. My 360 was at zero deck with 2.02 J heads and a purple 292. I made the move to the Edelbrock heads. A very nice improvement for sure.
I have pretty much the same thing on my 72 340 4speed Cuda.
I sent them to IQ52 and had Jim,
And Cody do their majic !!
Very pleased !!!
Jim
