hi.
does anyone no the standered lash measurements for the sti bigport 2.0 avcs heads ?.
would this change for supertech inconel valves?
i have fitted new supertech guides, ive also got the supertech exhaust valves but unsure if they will have different lash measurements as the are made of different materials, from what ive found on the google cossy crowler ect run different sizes to standred but cant find the standered size. any help would be great. thanks phil

 

Are you running OE cams or aftermarket ?

 

standered cams jdm spec c

 

The clearances will be 0.2 inlet, 0.35 exhaust, no need to alter from oe spec as heat dissipation will be better with the bronze guide & better valve quality.

 

thanks for that buddy.
