Harmonic balancer has no marks I think I’m TDC

I pulled engine a couple months ago replaced all gaskets and rear main seal had heads re surfaced but I didn’t change anything internally. My main question is I get spark and it appears to get fuel but no ignition, if I keep cranking on this without ignition what am I going to break and what do I need to do??
Like I said it appears I’m TDC on the right compression but this my first build

Head bolts washers

Im Just about to start reassembling the top end of my 89 C4 and i have bought a set of new head bolts for the car as the old ones were pretty degraded. The set is got was from fel Pro and they look great but have a different shape to the oem ones and have no washers of course.

My question is can I A: re use the washers from the old head bolts (assuming i can get them off) and B: if I cant do that what washers should I buy to replace them.

I will get measurements of the old and new head bolts to ensure the washers will be compatible.

This is my first engine rebuild so im learning as I go along with help from my mate who owns 8+ 1930s American cars here in the uk. His knowledge is limited of course and the most modern engine he has re built was a big block in a 69 el camino so any help would be awsome.

Cheers

Is this ok?

Im rebuilding/refreshing this small block chevy its a 1970s ish block and heads rebuilt by Jasper a while ago my grandpa had it in his Biscayne for about 20k miles. Tearing it down to put in new valve stem seals I found these cracks from where new valve guides have been pressed in. THE CRACKS DO NOT GO ALL THE WAY THROUGH. They are only on the surface where it was drilled thin and new guides were pressed in but i am curious if it will be good to send it anyways. Im not too sure how it ran/if it smoked before since it has been out and non running for quite a few years.

Header issues

Working on swapping a small block into a C4 Corvette, running aluminum heads so I need to run studs and nuts for the headers cuz bolts can walk themeselves out. Got these C4 specific headers, which fit in the car and can rest on the studs, but on many spots the tubes are too close to the studs and I can't fit the nut on. On some even the washer is too thick to get past the tube onto the stud. Woukd it be OK to dimple the headers that close to the main flange? Any advice would help.

Strange sound from headers

It’s on the passenger bank only, haven’t tried changing gaskets so it could just be that.

Anyone heard this before?
