what is your opinion this combo?

Hi, and apologies for my ingles


388Dart: the pistons are KB #UEM-kb191060-8 http://store.summitracing.com/partd...890201+4294891059+4294776938+115&autoview=sku
this piston have 0.150 in. pop-up crown design with 0.050 in. elevated quench pad. The rods are stock and I wrong my head they aren’t mangnum, I don’t know exactly their characteristics are: the Spark Plugs is the same a Ford (big hole) add some pics of the head:




The timing: total 32 with 92 oct, 36 with 110 oct, here in Mexico is 8,202 feets.
The RPM 6,000

MOPER: I can’t calculate the compression radio yet, because I don’t kwon the combustion chamber (cc) of my head. When I put the head without gasket and move the engine, the pistons touch on head and then put the gasket and move the engine don’t touch. Add pic from the pistons.



Thanks
