Dart heads

I have a new stage 6 billet block and have just purchased a set of 1999 dart fuel heads. The problem im having is the pushrod fails on the head due to the angle of the push rod hole in the head. I run stage 5 rockers. My question is did dart ever do a head for the raised cam blocks as this would answer my question. Do they do a longer rocker to overcome this problem.
Thanks,
Tony.

 

I run a TFX billet block, raised cam, 2.000 spread lifter, Dart head "99", AJ black stands with dog leg, Stage 5 int & ex rockers and they clear. I think this is similar to your combo.

 

Block

Hi sandracer I have a standard cam stage 6 KB with stage 5 rockers on 99 dart heads. I think this is causing the problem. I have been told that they did not make seperate heads for raised cam blocks so perhaps i need these staggered rockers you mention.

 

Tony check your PM. Joe

 

we run a .100 tall tfx-92 block with a raised cam......stage v int/exh rockers, and the gold stands on the dart fuel heads.........no clearance problems.

 

Thanks for all the input seems my problem is standard block.
