I'm about to have the heads removed and worked
are there any tweaks to do while I'm in there to
get horsepower added?

 

port and polish if you have the money. otherwise maybe a multiangle valve job. should cost ya like 50 bucks. well, that's how much my guy is. depends on how many valves.

 

Can you tell me what a multui angle valve job is?

 

Valves normally have 1 angle cut into them (I forget - 45 degrees?) that meets the valve seat in the head (which has an identical angle so the 2 seal perfectly) when the valve shuts. A multiangle valve job will cut more angles (at least 2) into the valve sealing surface so that instead of looking like this:

|____
.. . . .\
______\ <---

... the angle will be more rounded off, which will improve airflow. (man, was it tricky doing ASCII art )

 

I'm mad impressed!!!!!! yeah, my jeep had a 4 angle valve job done it. i hear you can do a 5 now but it depends on the number of valves. the more valves, the more noticeable this will be.
