Yeah, just think of the valve seat as a tooth in your head.....and think of the gumline behind that tooth (in your head) as being the same as the aluminum directly behind/under that circular valve seat.
No way in heck would you take out a knife and whittle on your gum......don't do it on that anchoring aluminum either!
(I like analogies.....would you like to hear some about women?.....probably not!)

Thanks Dakota!
I'm sure you could save me a few years of aches and pains in the Womanology Department of Science

I thought ALL of these "presentations" were of the same model.......THEN, I saw the valve guide.........

The head I went canadian ham on was the 77. The 91 head I just went around the bowls. The pic where the head is taped like a bomb to now is the 86 head original to my block that is surfaced and valves already ground. Did I go to ham on the guides? If so it's the rotary in me taking over trying to peripheral port ffs :/

Looks good! I wish I'd spent some time and ported my head on my AHU before I sent it in to get it overhauled.

Thanks!
I have now 100% made my choice that Thompson Auto Machining in Nanaimo BC is horrible. I'm new to piston engine rebuilding as this is my first so everything is a learning process so far.
I want to know when you guy have a rotating assembly balance would that be crank and rods or just crank?
When you have a "basic" valve grind would they lap the valves for you before throwing the head together?
My valves also felt tight to me and one intake was gritty feeling on the way out at the end possibly from debris I imagine.. I'm going by what my uncle says and they are feeling like they did no hone the new guides properly.
I remember asking the machinist about arp's in my rod's and mains when I was getting the block built and he said they are not worth it and reusing stock bolts is nothing to worry about but not what the manual says and some posts show what a failure looks like
I have to pull the rods out to replace rings anyways so the mains and everything come apart again of course and I get to figure out how to install all these bearings that I already paid to be installed -.-
Lessons learned yes and I should have done my research/bought a bentley before doing a rebuild but I still say some bad advice was given and work was done and I'm no rocket applientist.
I'm lost for words on my build. I know adding money up doesn't mean anything but at this price I would be half paid off a 2014 vw. Saving a old school is painful I guess but man. Just mannn.

i've seen lots of rod bolts being reused, they are stretch bolts and 1 time use though, oem bolts and arp are about the same price too which is good. might as well polish the rods while they're out ;^P

Yeah the mains are absolutely not to be reused. They aren't super expensive either way you go. Rod bolts seem to be debatable depending on the engine, I don't think they were TTY on the early engines but they definitely were by the AAZ for instance. But yeah after spending all the money on the rebuild it makes no sense to cheap out on fasteners.

Thank you guys I really really wish I just recorded my phone call with the machinist about 5 minutes ago. No kidding I swear he was fighting me over the phone and literally shadow boxing angry sounding in the voice.
He said everyone on the forums are idiots(bad words) and have no clue to what they are talking about. I switched conversation to the valve guides being very tight in a few and gritty on one especially. All he said was bring it in for a sample to be assayed and went dead silent. I've already cleaned them out obviously so I just can't be bothered with him anymore.
I'm just going to go to the other machinist and have all valve guides worked over for 100$ and he said it's worth the 3 angle grind. I already like this guy a lot more.
I would rather have new hardware for sure over any catastrophic failure.
I know what I can and can't install myself now and let's say i'll be saving a lot next build!

it's hard to find a good machinist. a lot of them are so cocky or not willing to do stuff as you ask because they are so set in their ways.

Yeah lots of people have gotten away with a sub optimal build and ended up with a running engine. But lots have ended up with something less than ideal which lasts 1/10 what a factory engine would have too. Fact is not a lot of people actually put a couple hundred thousand kms on a rebuilt engine before the body rots away, especially somewhere like Nanaimo where you can only drive so far before you hit water. That guy can have 50 happy customers who never got more than 50,000 km on one of his rebuilds due to geography,helps build false confidence big time.
