My attempt at speedmaster heads and moving the pushrod.

Litte progress update, spent some time detailing the chambers and the spark plug hole. Then turned my attention to the exhaust ports. Mainly just a port match and smoothing, did a little bit of blend work where the large divot is in the back of the port just above the seat. Also laid the SS over just a bit and blended everything for a smoot transition.

Currently waiting on my valves to show up so I can have the throats opened up for the 2.055 valves then ill finish up the intake sides.

I put just a hair of sealer on the cover bolts. Not sure it’s actually needed. Never had an issue.
 
Do we have a thread section for stuff like this? Like "how to" type deal? This is some real hot-rodding type of stuff!

Heads are back on my bench so that i can finish up the bowl / ss port work, then they willl be going to the machine shop for a valve job. I ended up getting all new Ferrea valve guides sized for 8mm stems, and will be running 2.08/1.6 Ferrea 8mm +.100 LS style valves. This will help with overall valvetrain weight and also parts availability. It will also allow me to run the BTR .660 dual spring kit designed for the LS, and will get titanium retainers too.

Ill try to get some more pics up here as progress resumes.
 
Small update.

Finished the bowl / throat areas on the heads, also went over all the exhaust ports with a crossbuff wheel ( 1st time using those, will be buying more). They are now ready to go back to the machine shop to have the valve job done.

Also spent some time on the intake manifold. Laid the pad to runner transition back a little farther for a better radius, then went through the entire manifold and put a burr finish on it.

We do have a how to section but it is not just not rodding and porting. You’ll also find electrical, body, etc….
 
You fellers that do this type work amaze me. Yall have the patience of Job.
