Update The Short Block is home! I have the Blueprint forms in front of me. The Diamond pitsons look great. Lunati 4.5 Crank looks nice too. The shop had adised to go with the 85cc AFR head over the 75cc sighting better flame path, quench area? I have a 4.5 stroke, 6.8 lunati H rods, compression height of 1.250, deck height of 10.305, calculated 10.3.The pistons are 4.3900, effective volume of -18cc and are set u for afr heads. does anyone care to calculate the quench area? Im sure i missed something, I will probably run the felpro head gasket .041.
I used diamond compression calculator and it came up with roughly 10.65 with the 85cc head and 11.6 with the 72cc. please feel free to correct my circulations. the heads are next...which ones? lol
The deck clearance is -.006 + .041 head gasket, does that indicate .047 quench area?

Reason: quench calculation
