1.6 rockers,,, cause and effect

i dont have the correct valve springs yet, so thats ok, i have two sets of singles up to 500 lift so im in the market anyways. guess i need to check clearances with these numbers and see if the pockets are deep enough as well

figure put what the target installed height will be-1.70 or 1.75 or 1.80
I think the eddys are 1.80, so that'll open the door to an abundance of spring choices and cheap!
