I have a 95 GSR Engine and plan on installing some Toda Spec. C Cams. I plan on using the Toda Valve Spring set and some Titanium Retainers. My Head, however, has been milled so my current compression is 11.2 to 1. The Pistions I am using are the Endyn Roller-Waves ( Stock 10 to 1 Compression ). Seeing as how my Head has been milled, should I be concerned with Piston-to-Valve Clearance when the Spec. Cs are installed? I notice, Toda offers different Head Gasket thicknesses, Link: http://www.todaracing.com/B16A.html . Would the thicker gasket solve my Piston-to-Valve worries? Any suggestions or solutions would be greatly appreciated. Thank you.

 

Yes, I would be concerned. Get the clearances checked. The thicker gasket might do the trick. Try it out, good luck.

 

u could test your clearance using the clay test. assemble your motor put some clay on the top of your pistons crank the engine manually till the cam's make a full rotation and mark the clay. than all u have to do is measure the mark left in the clay and you'll know your clearance.

 

With the Endyn pistons I dont think there should be a problem. If you install a thicker head gasket then you will lower the compression and that defeats the purpose of milling the head.

Contact Endyn and se what they say.
Or do the clay test like was mentioned. Its kind of a pain the *** however.
You have to remove the head, put clay on the pistons, put the head back on, torque everything to spec...then take it all apart again and reassemble it again.
Although I guess its beter then bending a valve huh?

 

Thanks everyone. I appreciate any ideas you can give me, as I really want to use the Spec. Cs in my engine.
