hi guys, i need some help on this, i plan on running trick flow 23 degree heads, pretty sure my pushrod is 3/8th, motor is a 89 l98 block, do i have to use the trick flow narrow rockers, they are $299 , i dont plan on using stock valuve corvers, so clearance wont be much problem i suppose if i went with cheaper rockers, but what will work ? i see the crane rockers all the time but they dont give much info on if they will fit centerbolt heads, if i could get a set for $150 instead of $300 ,is what im hopeing, allso i have heard that roller rockers have a life span of only 100 thousand miles, ? is this true,

 

I have the same setup as you TF Heads 3/8 pushrod 7.3 length centerbolts and I went with regular SBC comp pro magnums. They are small enough to fit under centerbolts. I went with PN 1302-16

 

sweet thanks man, how much did they cost ?

 

259

 

only 100,000 miles??? how far u plan on driving???

BTW id run some harland and sharp RR's. I think they just came out with a narrow body set that is lighter then the regulars. They are cheaper then crane golds too but plenty strong.
