Its Friday, and I had a good day in the shop. First two pics of the finisher ports. Cleaned the heads, and assembled. I blow the guides out with carb cleaner, air, then lube, assembly lube, and Lucas, as it is so sticky and stays on the stem. It is nice having the valves in, but cannot install the pushrod guides, rocker arms, until I get my cam......but it came late this afternoon.

I also notched the block to help with intake shrouding, 1st two pics. For those that want to know, stay .06 off the top of the ring, and use your head gasket as a templet and scribe a line. I had hard stones on a die grinder, and finished with the finest cone I had, but pleased. Why? worth about 10 ft. lbs. of torque, and 13 hp at 6000 rpm. We'll see how it works. My block mods are now complete. Pan came today. This pan has been tested, and is worth hp, and a nice piece. The power is made through oil control, which I have taken pains to address if you have been following along. Test say this is worth 9 ft. lbs. tq, and 11 hp. See, just made 24 hp.

I like a positive retention of the cam bolts, and ARP bolts for the head. Fit perfect.

The engine brain cam in today, a few pics. In retrospect, I wish I had gone solid roller, less trouble with solids, and much higher lift. Disappointingly the Johnson lifters did not come like they were supposed to today. Cam is beautiful and should work good with this combo. I had to use more duration because the heads are a bit small for this engine. However after the porting, and block mods, hoping for an extra 20cf. If I can pull strong to 6500 rpm's then I know the heads work. Probably more like 6200 rpm's. I will go over the cam tomorrow with a stone if there is anything that needs deburred, but I doubt it.
