That's a bummer as he is tight on funds and does not want to pull the engine, change pistons, etc. At this point, I guess that it would be best to use a head with a big chamber and run a thick gasket. Mortec.com says that an 049 head has a 122cc chamber, maybe I could round up a set of these on Ebay or find a cheap set locally. We will probably try this and a different cam, could you recommend a cam to bleed some of the pressure?
Thanks,
Steve
