Hey guys, I had Tony send me a set of these heads for my 416 build about 6 months ago for an all out S10 build. Mamo ported 102, Mamo specc'd cam, Johnson lifters, etc etc. The only thing I probably skimped on was the powerbond underdrive pulley.
It made 660/590 on the dyno after the break-in cycle.

 

Nice what cam did he spec you and what CR . I'm in the process of a Mamo build also.

 

It's been a while but I believe it was 247/252 and the CR is a hair under 12-1.

 

Very nice. I assume that S10 is going to be light as **** too.

 

It's a second gen so not quite as light as I would like. I haven't had it on the scales but I'm guessing a hair under 3200#. I'm going to do a blazer tank swap and install the battery as far back as possible to help weight distribution.
I'm also wondering what an Edelbrock proflow or Holley high ram would do to the curve. It might be better to lose some on the bottom to gain up top, maybe even go with a LLSR if it's worth it.
