Not bragging...but we have 5 more boats between our family. We have learned that at least 2 are broke down at the same time.

Well...funny you should ask. Lil R has boat ready to go. Tyler has entire port engine back together, but still waiting on a custom cut piston to fill the #4 hole that needed bored out.

The NEW schedule is to fly down to RF again the week of Oct 3-7th. Tyler i supposed to get down there that Monday or Tues the 3-4th, if all works out. Lil R and Tyler will install engine, and re-test..and hope it doesn't blow up again.

Then it goes back to MO, gets driven once or twice...and then on the rack for the winter....lol. At least we saved money on gas this year.

Keep your fingers crossed guys...I know I am.

Tyler, it really appears you will have covered the basics well. I'm sure this is a stupid question, but are you 100% sure the head(s) and block are straight?

And FWIW, regardless if the lack of studs is associated with this reoccurring issue or not, I'm shocked they weren't in there in the first place!
you'd actually be surprised what an arp headbolt will hold up to in a 540, i sprayed one with 500 hp worth of nitrous for over 150 passes never blew a headgasket, granted i pulled the plugs and inspected with a scope every pass and it was only 8 seconds at a time

If it were me, when the engines go back in the engine builder would have his laptop hooked up looking at the called for timing numbers and being verifyed with a timing light First through out the rpm range under no load and then again while under load.

Ofcourse most engine builder will not like this comment because who wants to be in engine compartment at speed with lots off hot stuff and turning belts. Most would agree to due it on the dyno, but ultimately the engine lives (or not) inside the engine compartment.

timing light will not show individual cylinder timing, msd digital ignitions have a provision for adjusting individual cylinder timing. since he had one piston burn and a few others fine my w.a.g (wild a$$ guess) would be detonation. the actual timing degrees is just a reference number, the heat mark or line on each plug electrode shows how each cylinder is firing/ heat in the cylinder. some applications i had to retard cylinder 7 (2)*
