Cut the valve pockets today. Yay!

I have the head drawing from the TR manual do I know the valve angles and I have angle blocks

The ground rod I got from mcmaster was a couple tons bigger than the wrist pins so I sanded it down

I measured the radius JE used and found the boring tool that matched

I set up a scrap piece in the vise and used it to set the boring diameter to .100" over the valve size to give 0.050 clearance per side

Then I picked our the piston with the worst looking valve marks, bought the cutter to the mark an moved over 0.050 and cut

They went quick then I changed over to intakes and realized something wasn't right.....the setup piece was centered the next was clearly not?....ahh the vise is moving, add shims the recut everything just to be sure

I notice a couple odd things. The angle on the exhaust pockets was 20 not 21 I think and the spacing on the intakes was 36mm (exhaust side) not 38 but that is all fixed. The piston I realized the lose vise on is ok...but I have 1 more new piston so I'll just replace the does look quite right one. Job done now I can rebalance them

I opened Dynomation this morning and installed the latest version which brought me sad news.....I'm down to 805hp. Honestly that number sounds way more right than 920 but I like the 920 sounds way better :)

.....I guess the good news is I have an 800hp dyno so maybe it doesn't need an modification to work.

Taking to Wade about sending back his vise and he was all but you didn't clay them yet, what do you mean your done?

....fair enough. I think I found enough bearings to get the crank in good enough to check the pockets so that is on the list. This engine is a pain in the butt to assemble so this is about 10-20hour deal....but I want to be sure it's right so....

As I was washing up I realized there is an issue with claying the valve pockets....there are no exhaust seats in the heads yet. I guess I'm kind of out of excuses not to finish the head at this point and I kind of need then done so heads next.
