I confirmed the head gasket was the standard head gasket that came on the SR20, I asked the seller
I had zero problems with clearance. The biggest pain in the arse with the C cam install is keeping the valves from falling and you need the compressed air w/ hose in the motor -
The C cams, along with a JWT ECU, header, intake, and exhaust, made a new type of GROWL. I really liked it. It sounded awesome. I have some videos somewhere of the car @ WOT showing the tach, will see if I can find them and post them here. Again this was on my 10:1 motor, damn I miss that car
BTW this is what it looked like in the end. The motor/trans were good but the car was done. I put it in spoiler tags for B13 fans who are faint of heart
