I now know you hate yourself. If you didn't, you wouldn't put yourself through all this!!
I do like following along though.

What heads are those? I like them!
Small block Edelbrock heads with pushrod holes plugged and moved over .300 or so.

Fun to watch the progress...... but that’s a big “no thank you” from me.
is that just for the porting, or to get bigger valves in? or maybe both?
To relocate the pushrods with offset rockers like in W2 heads, no more pushrod pinch point.

Friggin sweet!
Don't mean to bug you with a few questions here, but love seeing stuff like this (followed yours and others work in other threads, learned quite a bit along the way). Are you going to run 2.08's, or..? Who's rockers do you end up running when you go offset like this? Last but not least, will you post flow #'s for us to ogle...puh puh please? Certainly understand if you take a vow of silence.

After he lets us know the valve size, who wants to guess what this big joker will flow?
Harlan Sharp made me up eight 1.6 ratio rockers with .350 offset to see if by moving the pushrod over I could beat my best flowing Edelbrock Head at 318 cfm with the same 2.08 valve.

I believe your going to easily eclipse that mark. 340 cfm would not surprise me at all.
Heck I didn’t even get 340 out of these
360-1 Indy’s

325 would beat the guys running their "big mouths" a little West of you
Do you end up having to drill the new pushrod holes at an angle, or how does that part work?

Still very good looking work. I am curious to see what the low and mid lift flows are on this level of Edelbrock head. Do you have the numbers on the 360-1s?
I’m not even thinking that far down the road. My Harbor Freight drill press has an adjustable angle setup on the table so that with probably be getting used.
Somewhere around here but they will be coming off my 422 soon. It went a best of 5.98 and a handful of 6.001’s@2880 pounds
They will be getting more work over the winter but I’m only running a .650 solid lifter cam.

How do those compare to the offset on a W2?
I wish I would have picked up a set of the SM during to sale to play with and maybe learn something like this. I’m starting to see how much work it is though. One port isn’t bad but you need to duplicate it eight times or you are peeing into the wind.

Man that's good stuff

I think the offset for the W2 is .750 but I'd have to run out and measure them for sure, and it's too late for that tonight.
.750 it is.
