Totally missed this thread. NOW the email and post shortly following in a thread here about the buyer backing out makes more sense.
Simon ,glws, and new owner can buy with confidence in the engine kit you were putting together. Seeing we made 180whp/180wtq with all same parts (except 8.8:1 pistons vs 9.4, and 81 vs 84mm crank: aka 2.7 vs 2.8) this is a good buy. That head and a 10.4:1 engine is going to be very potent and reliable (adding stroke increases static compression). We will be dyno-ing this exact combo soon enough (and adding it to the ForcedFirebird m20 Dyno thread). The original head didn't purchase flow data, but we typically see a 10cfm gain (184-ish cfm with the custom valve job and throat angles). This same exact head work is powering a 208whp m20b25 with Shrick 284, 12.5:1 comp, and has been sweeping the SCCA ep class for two seasons. All the heads we build have serial number stamped in them, and documented where they came from, and where they went.
For the future buyer, the pistons are on size, so if you have good bores in the block, just need to deglaze, but technically should remove .5mm from the block deck to get 1mm for quench, but even if you don't, you are only loosing about .5 compression.
Apologies for the thread jack, but like to be thorough with parts we built at the shop. :)

Don’t apologize. I’m actually secretly hoping that nobody buys it, I finish the motor and get a windfall of cash from Somewhere else so I can keep both cars and live it up...
