Yella Terra installed Just put my new 1.7 ratio YT rockers on last night (Thanks Mark @ Ragingmotorsports for that kickass GP). They are a VERY nice looking piece of hardware...thats for sure 
Was able to maintain the 7.350 pushrod and it required no shims which netted me ~1/2 turn of preload on the lifters.
Valvetrain is pretty quiet (it wasn't too loud before them either). Obviously a less than 10 HP gain usually don't gain any SOTP so I can't tell but it does seem to rev smoother

Re: Yella Terra installed FireBall - Shouldn't you have had 3/4-1+ turns of preload instead of 1/2. Seems a bit low to me and could cause some valvetrain noise. There is a current thread where this is being debated as we speak.
Nassau Joe - Just so you know 100/1000th=.100" and 125/1000=.125" just thought it would make it easier to type thats all.
