YT's, Comp 978's, and FM13?
 

I have a set of new AS 5.3 heads with 978's on them. Jay supposed to set them up so they are a little stronger than the posted pressure for them, but he has fell off the face of the earth and can't confirm that. I'm running Yella Terra rockers and want to know if they are too heavy with the FM13. I really don't want to put the stockers back on. What are the other options, or just leave the YT's alone? Thanks.

Im interested in this also. My TEAs have 978s and Im running the X1 with YTs too. Figuring on the FM13 or FM14. I dont think there will be much differance. Thats why upgraded to the 978s in the first place.

the X1 is about as big as the 13 so that looks good for the 978's as your car seem to run pretty damn good! :D

Anyone else?
