70 pontiacYU350 with #62 heads

[lomchivok]

Got a 70 Pontiac 350 YU block..a good runner with #11 heads. Have a set of #62 4bbl heads with 2.11 and 1.77 valves with 72cc chambers. I know the comp will be high with today's pump gas but figure a thicker head gasket may get the ratio down enough.

Will there be a problem with the big valve heads on this 350 block as far as the valves contacting the block...What cam would you recommend?

thanks in advanced...
