can someone tell me what the valve clearances should be on sti4 heads with under bucket shims?? ive searched but cant find anything

just built a 2.5 to go in my 94 wrx, the silly sod iam didnt check the clearances while it was out on these heads which are new to the car as i bought them second hand, got the tappet tickin noise and want to check them before i put the car on the road, some of the noise is the wiseco pistons but that quiets down as it warms up but the tickin seems to stay, it has got better but its still there


cheers

Darren

 

Should be 0.20mm inlet and 0.25mm exhaust i think used these figures for my STI 3 heads and i'm sure they are the same .

 

They are the same, I have just set my V4 shim clearances to these gaps
