I am in the process of swapping the heads on my 1955 TBird.  The engine is the stock '55 292 .040 over and it runs well.   I have a rebuilt set of 1957 G Heads, '57 high ratio rockers with the longer push rods and a 1957 "D' code iron intake with a new Holley 4 barrel. I also have the a set of '57 exhaust manifolds off a passenger car.

When I removed the '55 small port heads, they had metal oil baffles under the rocker stands.  I worked on a number of Y blocks back in the day and have never seen them before.   I assume I should not use them on the '57 heads and rockers?  There seems to be a number of thoughts on this. I plan to close the end of the oil drip tubes to pressurize the rockers. 

I am using Fel Pro blue head gaskets on the '57 heads.  What torque readings should I use?  Should I re-torque the heads later?

I looked at the G heads and the ports are much wider.  The valves are also bigger.  It will be interesting to see what difference these heads make.

To be honest, I do not see much difference in the '55 TBird Exhaust manifolds and the '57 passenger car manifolds.   I'm not sure they will fit my TBird and from the looks of them I don't think there is that much performance to be gained.  Thanks for you input.
