It is an R33 RB26. I have attached the spec sheet that comes with my pistons. I am looking at purchasing the Tomei Procams 270* with 10.8mm lift. I have a 1.2mm metal headgasket but it could use a changing do its possible to get a thicker one if needed. As far as i know, the head and block have not been resurfaced (I bought the car with the swap done and it was a bone stock engine but who knows...). The shop that built my motor said that the block/head didnt need a resurface so they didnt do it. I upgraded to Eagle rods that have 4.783 length which is stock. My main concern is slapping the piston with the valves. I purchased Brian Crower SS valves std size which are already in the car with no issues. Is the 10.8mm lift too much? Or should i stick with the 10.25mm lift for those cams. I have also attached a picture of the stock rb26 camshaft specs.
If you could help me out with this it would be greatly appreciated.
Thanks
If i forgot anything please let me know.
