215 oval ports (219/188)&ported /shaved
JE forged pistons 10.25-1 cr
UD hyd roller 288/296 234-242 .600 .600 on a 110 LSA. Matching springs
CC roller lifters
Crane 1.7 roller rockers
Cloyes hex adjust timing set
Performer RPM intake 1/2 four hole spacer
750 DP holley k&N air filter
Holley fuel pump
Mallory IGN

The lift will be .632 instead of .600...maybe 5 HP or so...heres a good link to a discussion on the change/or no change of duration.
