Thanks for all the input. After long hard thought, I am going to go with the 440 Source "Stealth Heads" which have an 80 cc chamber. If I use the KB 184 piston (I now have the 237 and both are a silvolite)i can hone and not bore. The quench pad on the 184 is .140 tall and I figure I will need to have half of that removed to get in the ballpark of .040 to .050 quench and should have a CR of 9.6. I can also deck the heads to get the CR up to 10 if I wanted and still have optimum quench.
Yes my heat risers are blocked and I appreciate all the tips but I feel if I start out with a better combustion chamber design to begin with I will be better off in the long run. I will post again in about 2 months. Anyone have reservations about the 440 Source Stealth heads??
