I have milled 318 heads .090". It made them pretty close to closed chamber heads. The pistons still were about .1" below the deck though. But no problem with the heads with that milling, except that you had to take that in to account with the intake fitment and the blocks end rails. If you mill the intake faces, the valve cover rail may become really thin.

I have heard stories from back in the day when local stock car guys racing flathead Ford v-8 engines would heat up the cylinder heads and add brazing rod to fill in the chambers to raise the compression. Then surface them as much as possible.

What little i know about porting learned from Tim Connelly worked at dyno center at dodge he said pretend its a road you want a smooth road. And never gasket match port match gasket matching usually causes a small valley makes turbulence.

Very interesting topics. I'm always looking forward to the next info packed video.

This may sound silly but why not start with an 85-91 318 block and heads? They have smaller swirl port chambers and roller cams. I know this is the block Junkman Tony saddled you with but you can still trade. Part of budget builds is starting with the best factory pieces to fit your needs. The price difference between a 1973 and a 1987 318 is negligible in the wild.

Love the Mission Impossible series.

Hi David , everyone involved with this has and is doing an awesome job to the motor and for saint judes .. my question is , ( remember I’m an Aussie 😅 ) with cast heads can you weld cast heads to fill the chamber up to boost compression instead of taking 100 thou off the head to increase comp .. this will also effect valve geometry ( as you would know ) plus old school mechanics do say it can heat your motor more ?? Apparent quench part of the heat distribution of the head.. cheers

2V heads had a poor open chamber and reasonable ports while the 4V heads had a good closed chamber but the ports were to big for anything but high rpm race use. The Australian heads were a combination of the 4V chambers and the 2V ports. When combined this way the results were positive.

Heads went from the earlier wedge to the open chamber for smog reasons. Now you can make them work at high rpm (above the torque peak as in drag racing) and with octane but they suck on the street. We used to weld up those chambers then developed special pistons Today you can get aftermarket heads with much better chambers or use Magnum heads I would never use an open chamber head on a street or motorhome or marine build. I hate detonation. MA Mopar kept dropping the compression which requires more throttle to make the same hp and makes more heat. The cam that came with those heads had a really late close to give a faux egr input charge exhaust dilution also makes heat. You cannot make those heads without creating quench. You cannot make those heads work with any cam without race gas unless you do not use throttle at lower rpm, YOu can fly cut to equalize the chambers then use dome pistons into the flycuts with a dish on the non quench side (to give whatever compression is desired). I would only do this on a matching number restoration ( i have done on 340 but not on 318) It's easier to get the piston pop up with a 360 crank in a 318 or 340. (or 20 years ago use a 4" stroke 10 years ago I'd start with a MAGNUM If you are running a .450 lift cam try a cut down oversize valve with a 30 degree seat Looking fwd to discussion of valve heads and smaller stems. LA has short spring height so I usually install longer valves and relocate the rocker shafts which needs to be done to get the geometry right anyway
