STI V 3 Heads on a 1997 WRX
Hi Guys ,
I just installed a set of V 3 STI heads on my 1997 WRX and it the clearance may be out as it seems that some of the valves may be just touching the pistons when i turn the crank , Doing some research i found that the V3 cam lobe height is greater than the standard cams .
Do STI pistons have like cut out sections or something to accommodate the extra lift ?
Is there a way around this without changing the pistons , Like are there thicker gaskets or something else i can do to solve my problem with out changing the cams , Any help would be AWESOME .
Thanks
Chris .

Sorry i dont't know by mm all I know is i asked the supplier for head gaskets for a 1997 WRX made in the 6th month .
Yes the car is in neutral ,
Yes timing marks line up but One thing i did notice is when i crank mit round once the timing marks are good , twice all good but the third time the bottom mark on the bottom right side shifted a bit to the right but when i turn it all the way around again the 4th time it all lines up again , Could that be a problem ?
Thanks
