Although I am getting closer to the center of the valve face, You can see my sweep is getting wider. Pretty much doubled.

You can see I am getting further towards the intake but loosing my 90* to valve very quickly.

Still pretty darn near 90* to valve. This is the optimum pr length for my set up. I am in the market for 7.5 +/- . I havent found many that length but havent looked that hard.

Here is half lift. Finding out that when 90* to valve, you dont achieve much sweep.

This is where that got me. Too close to the exhaust side. I still ran through the motions, closed, half, open to see and also record my sweep marks.

Then I adjusted my pr until I reached 90* to the valve. I then did some basic math to figure how many turns on the poly lock to get me down half my lift. I started with a 7.6" pr.

First, I established half lift. You can see I will be needing longer studs...

Shaving .065 off the heads improved the position of where the roller sits on the valve face. this is at zero lift, if you draw a straight line from roller pin to valve face, you can see it sits just to the inside. at half lift, it is centered and full lift, just to the outside. Will work for me.

Both heads installed and torqued down in 3 steps. 25-40 and a final of 65. I put arp thread sealer on threads and their torque lube under washer and bolt head per arp recommendations.

Driver head set in place. I am really digging these 26918's. I do have a set of pac's 1218 I got for a good deal in case they dont work out or I dont like. But so far so good. I could easily go to .600 lift if I wanted. Plenty if retainer to seal clearance to boot.

Here you can see the intake clearance. I had over .160 at its thinnest place.

Here you can clearly see that I have plenty of clearance, both from the radius and the face of piston. I believe I had over .250

Checking cam. Ended up getting a roller lifter from napa and converted it to solid so I could check valve events and PTV.

Here you can see the roller sits just on the inside of the valve face. If you draw a straight line from the roller pin, it is just off to the inside. When at half lift, it is centered, and at full lift, just to the outside of face.

As you can see, the roller sits almost perfectly even on the valve face, side to side.

Rocker geometry is perfect. Shaving .065 off heads moved roller and greatly improved its sweep across valve face.

Both heads on and torqued down. 3 steps, 25, 40, and a final of 65. I used arp thread sealer on the threads and their lube under washer and bolt head as recommended by arp. Rockers are just set on.

I'm really liking these 26918's. I could go easily .600 lift if I wanted. I have a set of pac's 1218 also in case I dont like these.

Intake clearance. Obviously I will subtract .010 for crush. Gasket measured .0376 and its installed measurement is .028. I believe I ended up with over .160 clearance from the radius. Plenty ptv.

Exhaust clearance is easily seen when using clay. Have over .200 clearance on exhaust.

Another angle. Need to get a oil temp gauge. Will prob plug this hole in the mean time.
