I got a set of 327 heads with the 62cc chamber and 2.02/1.60 valves. the heads are really ported and polished the valves are manley stainless swirl polished. and it has push rod guide plates and has been machined for the newer valve seals. i think the valve spring area has been shaved down.

well i want to run these on my 383 buit i have to drill them for the acc holes so i can run a alt, the ps i can do somethin elce. and i need springs and retainers.

 

All those upgrades mean nothing if they're on shitty heads. What's the casting number? The fact that they're ported could be a big deciding factor, but no one here will know the flow numbers for them. And how far they may be from stock. It may be barely better, it may be a lot better. But cylinder head tech has come a LONG way since the days when they didnt have all the acc bolt holes drilled. They may work okay, though.

 

3782461- codes says 64-66 2.02/1.60 62.076 chamber

well behind the valves themself its all smooth and clean. no humps. the intakes can be taken more but its seems to be a good port job.

and i think 160cc runners
