Hiya,
I put the engine together in 1990 but I changed crank twice (With new bearings) and cam 3x. New bearings when I first put it together.
No 1 plug does fire. At least out of the block. Spark is blue.
Compression on no 1 is 138
Compression on no 3 is 140.
I checked twice.
I got those heads just a couple years ago Guides and seals should be good Well, they should.
I quit watching the odometer a few years back. With the rear gears the speedo isn't correct anymore.
