I'm curious what, if any, these SM heads will have over the Magnum heads I also have to replace the stock 360 heads on the engine?? My cam is really small .427/.455 lift. The mag heads will use 1.6 rockers which will add lift along with flow, and compression. I think the SM heads will flow more, and save weight. But how much more???
 
I’m sure you’ll provide us with the answers to those questions when the weather breaks.

still waiting for the dragway to release the new schedule.... Usually sometime in April they have their Spring Warm Up/Swap Meet that I almost always go to.... look over the swap meet and whatever I drive there I usually make a pass down the track. So we'll see, it'll be here before we know it.

So true. I always say you have to think at least 60 days ahead or you are behind. March will be right on top of quick like. You just can't plan far enough ahead.

For me especially, until I get a garage of some sort built, I'm outside doing my work. IF I had a garage, I have a lot of things I'd be doing for the next 3 months... LOL :D

Dang. That's born again hard core.

I'm just way too reading old to work in the cold so I heat in the shop. I dang sure ain't working outside.

You are a much tougher biscuit than I am.

30 years ago I was rolling around on gravel and grass.... laying 2x12's in front of the engine hoist. Now I got a concrete pad - 24x28' I'm like right up town now.... on a sunny day :D :D
:lol:

I'm with you there. Our garage was built in 1919. It's a double garage built for model T's. You pile in some lawn equipment and some tools and mom's car and I am out of room. I do most of my work outside in the summer or hire it done in the winter.

I tinkered with my spark plug hole today.

My first duster was done out in the driveway and I remember putting the B & M shift kit in in the backyard in the grass..
Don't drop one of those check balls in the grass! LOL..

Could a guy use a countersink bit for the plug hole? Thanks. Kim

I don’t think so. Not going to cut worth a crap on that angle and it would be too wide by the time you got deep enough. Easy with a burr or drum.
 
Hey, I was thinking about this earlier, what gaskets do you recommend and do you use those for port matching?
