Hi, guys... I bought a pair of ECR heads... What are the specs on this Heads?
I read they had the same intakes valves likes 1957's models 1.92" and the exhaust are Sodium filled... Exhaust valve sizes are?
Low compression heads, large Chambers? Thanks in advance...

ECR Heads are very low compression (large chamber), large port, big valve (all that I have seen), these came on H/D 272 Engines, not good for anything short of supercharging.

Many thanks!! If someone now what could be the compression? 8 to 1 or less? I appreciate your help!

292 HD truck combustion chamber
Ford 292 (Phase 1) made in Argentina
As you can see in the images there's a big difference in the combustion chambers heights... Argentinian made Y block only 6.5 to 1 compression...
