Yeah, me too LOL... So major-ish set back. I started digging around looking for info on my current ancient NOS PTL heads. Apparently the heads were not decked to restore the chamber to the 63-64cc advertised on some of the heads, like mine, that received the 210 CNC program. So the engine has 67cc heads and 16cc slugs .016 in the hole... 8.4:1 comp is not good off boost. LOL! There are some other issues as well, these heads were designed for the 8.2 deck (289/302 and variants) ONLY and do not properly fit my 351W (9.5 deck) or at least the intake and heads are not compatible. See the coolant leak stain coming from the rear water ports on the last pic... thats due to a casting error that allows the 351W water port to overhang the head... and leak coolant...So I had another set of heads delivered from ProMaxx Performance here in the US. The castings are off shore and really nice then they do all the machine work and assembly in TX. Pretty damn nice heads for the $! 60cc ports (1262) @ 180cc no CNC work to the chambers. I will pull them down check the 5 angle valve job, seats, bowl work, match them to my enormous intake LOL and re-assemble with the correct springs/height for the cam and ARP 7/16 studs (they come assembled with 3/8 studs and adjustable guide plates). But as they sit out the box they are VERY nice. I also ordered a fresh 8.2 .040 block for Roadkill so the forged 333 is going back together using the PTL heads and all my extra parts from the Panther's 351W that will fit. So no money "wasted" just another engine in the stable LOL. Just a huge time suck as the engine is ready (was) to sling in... Oh well. So no money "wasted" just another engine in the stable LOL. AND a huge time / $ suckI can't wait to see the videos when you get it all together...
