These new heads are the #61599 units which suit my flat tappet cam and have a 72cc combustion chamber, giving me approximately 10.5:1 compression. Smearing the ARP grease was a tedious job but I got it done to all 20 ARP stock-style bolts, then torqued them down to 45, 75, then 85lb-ft.
Now, I had a couple of fails. Firstly, I forgot to set the engine to TDC on #1 cylinder before torqueing the heads down. That’s ok, it’ll just cost me more time later on. The exhaust also cost me a bunch of time and effort realigning it after dropping the headers off to swap heads, plus i realised I'd forgotten to order a new valley pan gasket. The old one is torn to hell as the engine builders must've used some kind of King Hell sealant to make sure it didn't leak. I'll get that sorted in the new year, along with the intake and dizzy plug and the million other jobs I need to do.
Some pics with the intake and rocker covers dummied up. I still have to get the injector bungs drilled/welded to the intake, plus I need to fit rocker gear and sandblast the rocker covers as I don’t like the blue.
