cam install question
cam install question installing a new cam. currently have heads off with long block in the car. stock crank, cam and crank sprockets and katech timing chain.
aside from verifying the cam specs, should I bother degreeing it? I bought the cam new from a very reputable cam builder. realize you can do other things but I don't own a degree wheel and would have to buy one. thanks

installed cam and checking PTV clearance.
would the maximum clearance be when the piston is at TDC? My clearances were 100 thousands on the intake and 125 on the exhaust at this point. Well those are where the valve hits the piston. I'm just wondering if those clearances will get tighter during the engine rotation? Or am I good to go?
Hope this makes sense as this is new to me. Thanks

What is that crank sprocket degreed at from factory? I would change it!

Now you have me worried. Why or how can the timing chain be off?
I am running stock sprockets. I installed the chain by having the crank sprocket dot pointing to 12 and the cam sprocket to 6 - lined up. This put the cam pin roughly at 3 o'clock. This put number 1 at TDC and I had a piston stop attached.
There was some slack in the chain which I thought could change the cam by a couple of degrees but I spoke with Martin@tick who designed my cam and he said that was normal. I would think that slack would tighten once the engine was running?
