Are the wide squishband heads any good , unmodified .
Is the ' full Hemi ' the Normal stunt set up , or do we get ' creative ' .
Anyone got a machinists drawing , or plasticine and a scalple = Cross Section .for a Big Jim or other renowned ' tooner ' or the Double Star 60 ?
Thanks . ( The ones on the napkin in the 2nd photo are ' on the shelf ' ).
P.S. two of the motors pistons are ' whittled ' on the baffle centre / by plug. Thinking T L might be resposable , as they came from the states
( R C Motors tho. If TL says ' Does Modify them ' I guess they ARE o.k. stock , with gasket / squish clearace set .
