Out with the 340 & in with the 410 stroker!

Then what is the easy way to get to 260, what counts and what doesn't?

I understand you can't get a straight shot without relocating the pushrod hole, I completely filled mine, so I am about a third the way into it. You got a junk or spare set of heads to do this to, to see if it helps? Like I said before, I might be wasting my time, but just want to know, you know? I have only done one of the heads for now, so if the numbers suck big deal, they will get chunked for a set of rhs's, curious to see how it will be with the stock 1.88 valve and the large ports.
