it may work but i would have a set of 7.35's just in case.i have standard length on mine and they are milled .040 with a tr220 cam. it will depend on the base circle of the cam you are using.

you will have to call them to find out the base circle. if it is a smaller base circle you may even need 7.45's. i checked with thunder racing when i bought my cam. but they are also local to me.

Note that he's saying .20, not .020. BIG difference.
