Hey guys,
So I have an OST demon plus cam, see specs attached. I have a VVT limiter currently. Ost told me that it would be very close without a limiter on stock heads.
Now, I am looking to upgrade my heads to the Thitek with 2.200"/1.65" valves.

I have stock pistons, wondering if anybody knows if I will have PTV clearance issues.
Ost does not know, says that i may need lock the VVT.
Thoughts?
Help?

Thanks,
Rob

Looks like an awesome cam. HHP may be able to help with your answers. The lift is crazy. Thought 510 was a bunch back when I was building 340's.

I am doing one this winter. Everyone was so backed up and had a shortage of cores, I was not having my car down for months. I believe that I am doing a 3200 when first snow hits.

Yes, OST. But any tuner can tune a cam, just stick with the big names IMO.
