How good is the valvetrain geometry when using the rocker stand that etp supplies for use with the stock rockers?

Does their rocker stand totally correct the geometry or do you have to tweak it at all any other way?

Any other issues that don't let the ETP heads be a 100% direct bolt on out of the box?

all I know about them is that they are great flowing heads, hope you find out what you need to know. Good luck.

from what i found out today was that their rocker stands are A++ and the geometry is spot on because they et have re-done their head to 11 degrees while the gm one is 15 or 18 degree's
the above info was given to me by a site sponsor today as i was asking them about et's 3.9 bore head with 215cc
i have jesels and ask the sponsor why it would not bolt it straight-(rocker ?) i dont know what u are using by that was my ? to them today-

the rest of the head will bolt on apart from serious intake valve sizes that need big bore sizes- like for example a ls 2.200 intake valve will need a 4.125-4.155 etc etc bore size-thats the fitment factor-

on et website they will display the valves sizes on the head u select-so u are pretty right if u select carefully-

hope that helps-
