ok cool thanks. Yes those are the heads I`m using and yes there unported. I was torn between the Lunati CJ cam and the smaller Crower stage 5. I wanted to stay around the 220 to 230 split range at .050 duration and .500 lift the CJ cam had that were the Crower was .449 and .550 ish sorry forget exact didn`t want to get into alot of lift and need diff rockers and end stands to handle heavy valve springs. I`m hoping it will turn 5500 thats as high as I`m gona shift it no matter what. This is my at the moment motor for the FE race at Beaver Springs. I have a 63 406 trip motor thats gona be my spend big money on and do all out hopefully for next yr. I kinda thought low 13`s myself just out of experience building small blocks. Its gona go in the 12`s at that race cause I`m gona spray it that day lol it wont have a choice. Thanks for the help on this and I will def share what happens
