update on new heads.
I may be slow, I make many mistakes, and I may not be the sharpest tool in the shed, but I never give up. OK ,My motor is together, heads are re- torqued after a couple heat cycles. Been out for a couple test runs, and It sounds a lot meaner, has noticeably more power. I had to richen up the A/F mixture to accommodate the improved air flow. The only thing that is left to track down is a slight oil leak somewhere at or coming from behind the distributor. I can let it Idle and reve it in the garage for an hour and no drip. It only drips when I take it out and stomp on it real good. Ill find it, its just hard because it only leaks under acceleration. Ill check the valve cover gaskets, and re-torque the intake which should be ok as I did use hi temp RTV instead of the front and rear gaskets. I've already replaced the missing flat rubber gasket at the base of the distributor thinking that was it to no avail. Oh well I will get it, Its just enough to be a pain. Anyway I thought Id update for anyone who may have been following this project. You guys are great, don't ever forget how much you help knuckleheads like me.
Thank you .
Thank you .

Good work Jim
You might also check to see if its seeping out of the oil pressure sender threads (if the sender is located in that area). If so, try tightening it a bit more. Don't use thread tape or sealant on the threads though as the sender needs full metal to metal contact for an electrical ground.
Good luck

I believe so I'm running a pcv to the port provided for it on the Edelbrock carb, and have a filtered vent on the opposite valve cover. I did move my vacuum advance to the correct vacuum port left side of front, and moved the vac line from the c4 trans to the right vac port on front of carb. I will double check the Ededbrock PDF to be sure, pluss I cleaned out thee pcv valve. Thank you for your input, I always welcome and appreciate advice. Thank you QUESTION, are there different sized PCV for different motor applications.

For a non-emission controlled engine, you are likely to have better results using the Full-Time vacuum port (the one you connected the trans line to) for vacuum advance. Listen carefully for pinging tho.

I think sealer on the sender pipe threads is ok. Thinking back, I've only ever seen issues with Teflon tape on sending units (usually a serious over application of Teflon tape).

I appreciate that Bobby, my HEI has the o ring you mentioned, that I should have replaced it on principle alone. My motor didn't have the base gasket either, I just saw in on summit and was for a 302 so I ordered it grasping at straws. I was wondering how it would effect the meshing on the cam gear anyway, so I think it a good idea to ditch it and replace the o ring. I'm glad you brought that up. I can do that while I'm waiting for the new intake manifold gaskets. Heah who knows I may get lucky with the o ring. Sorry Bobby and lastchance53, Ive mixed things up again, this time with who posted what, but its all good both posts helped me.

If you are still having trouble get some UV dye. Then with a black light your leak will really show up well. Use it in total darkness for best results. The leak source will light up like a Christmas tree.
Here is just one source. Most auto parts stores have it too.
