Ok, I know everyone is going to post check valve covers and intake...been there done that and corrected (removed and resealed the intake and dizzy then tested with dye. Also replaced Valve cover gaskets and tested with dye).
Now here is where we are at.
Engine:383 stroker (Prior to assembly the builder had the block Thermal cleaned, mag tested, bored and honed to 4.035 with Torque plates Hellfire finish) Diamond Pistons 6" Scat H rods, Supercharged, AFR 220 Competition heads All Fel Pro Gaskets and ARP hardware.
I have poured in some dye and verified oil is leaking from 4 areas where the AFR 220 heads meet the block. They are on the driver's side under the head bolts near the second and third spark plug and on the passenger side near the second and third spark plug plus at the rear of the head where it meets the block.
The verification of the leak at the rear of the head was to tape a small white paper towel to the cylinder head and block. Only the underside of the paper towel showed evidence of oil and at the seam only not on the top.
After chasing down all the oil leaks and curing them. I then drove the car and my Spal fan controller stopped working (failed in the off position) I had over heated the engine for about a block or so. Thinking I had blown a head gasket but I have removed the heads (and am sending them to be inspected and decked as needed) but I cannot see any damage to the head gaskets.
I am wondering what head gaskets are recommended. Fel Pro 1043? Fel Pro 1003? Fel Pro 1142-026 MLS?
Obviously step one is locating the source of the leak and that can at times be rather difficult.
please forgive these question's, because I know youll think are stupid, but I'd need a direct answer, as Ive dealt with similar issues in the past
(are you sure its OIL and not coolant?)
(are you sure the oil pan , timing cover,or front or rear seals are not leaking?)
keep in mind theres zero pressurized oil flow passing between the head gasket block and heads mating surfaces. all oil entering the heads is routed through the push rods and drains by gravity back to the lifter gallery.
some cylinder head and engine block castings and some blocks that you might assume are compatible may not have the correct configuration to seal correctly and at times its not this obvious
