ok went to install new 1.6 roller rockers on heads and decided to check geometry by using the marker on the top of the valve stem. well my witness mark ended up towards the outside of the head.(pushrod too long). used a pushrod checker and seem to need one 7.1 in. stock is 7.2 on a hydraulic roller i think? well cant seem to find pushrods any where in this length they seem to only have them longer for some reason. any ideas ? am i doing this right?

thanks
happy forth to all !

if you can't find any the length you need you can have a set made to length

 

Comp cams lists a 7.100 pushrod. Part number 7938-16

JEGS High Performance

Set of 16 for $141.99 or

JEGS High Performance

Buy them for $12.99 each

 

Did the same procedure.
Just some info, my engine was a complete rebuild, heads rebuilt with 30' valve seats ( which sunk the intake valve a hair,) shaved .006", block shaved to 9.015".

Used 1.6 roller tip rockers, checked pushrod length and ended up with 7.050" length for the exhaust valves and 6.950 length for the intake valve. I ordered Manley pushrods through Scoggin Dickey, they were either $8 or $9 each.

They had to be sent directly from Manley and it took about 3 weeks.

Ouch

 

TrickFlow 21407100 are only about $90.

 

I paid 150 to have crane make me some. I went through the same procedure and needed 7.625" all the way around and had to have the custom made. now they sit perfectly in the middle of the valve stem tip.

 

found the trickflows from summitt online, 7.1" for $90.00 all is good. now im looking for valve covers to fit over my roller rockers. theres a pretty crappy selection out there for tall center bolt covers.

 

yep i was just gonna add that summitracing sells different length rods but i see someone beat me to it :-)
