Getting the Wheeling Fever
Ok, I just checked the timing and here is what i have:
7 Deg BTDC @ 0 Inches/HG with vacuum adv hose plugged and dizzy capped
VAC Advance check:
23 Deg BTDC @ 12 Inches/Hg with vacuum gauge/pump
12 Deg BTDC @ 6 Inches/Hg with vacuum gauge/pump
Centrif Advance:
16 Deg BTDC @ 2800 RPM.

I also sprayed some more carb cleaner along the intake mani and carb base plate and i do get a slight stumble when spraying it at the intake manifold right by the mech fuel pump. I also removed the hose from the out end of the filter and had a steady stream coming out of it from the gas tank being pressurized. I havent done the accel pump check yet to see if it is starving. Also i only have a vacuum pump in inches/Hg not Lbs/Hg. I am also hearing the hydro lifters ticking sometimes when i rev it up to around the 2800 RPM range but no all the time. I am thinking about just replacing the head with a clearwater head if i find a crack when doing the intake manifold gasket this coming weekend. What do you guys think so far? <img src="/forums/images/graemlins/patriot.gif" alt="" />

Getting the Wheeling Fever
Ok guys, I got the engine tore down to the block now. After pulling the head i realized that the 2 of the intake valves had a whole lot of carbon on them. The hyd lifters were making a lot of noise lately and i guess my comression loss was due to the int valves not seating properly. I also found out that this thing has a BSE kit installed already and i see cross hatch marks on all the cylinders still. Regardless i am still going to inside mic the bore to make sure it is good before i put the head on. I am also going to replace the chain and gears while im in there. The next main question i have is: Should i order the clearwater head with the mechanical rockers or the hydraulic one? Will the mech rocker head work just fine? I dont mind adjusting them every so often.

If you don't mind adjusting go ahead, the hydraulic work just fine for me.
