1.7 and bolted right up to my '79. I just torqued the rockers to spec as there's no valve adjustment on the '79 300 six.
Made the exhaust sound a tad louder as well. I didn't notice any difference in idle except I had to re-adjust my idle mixture and speed on my Holley afterwards.
My rockers were ordered for a '76 Chebbie 250. I used the pivots that came with the rockers, but my old nuts since the thread size was different.
