Yes rust in cylinders and on valves and seats is from fuel.

Todd, the VPC11 and C12 fuels will leave a little film of rust. Some light oil and a Scotch Brite pad and you'll be fine. I fog mine with Marvel Mystery Oil at the end of the season.

For valve springs, I'd highly recommend the PAC 1409X and matching their retainers. They were designed for this application. Controlling the lifter is critical with these stub nosed cams.

A good high zinc oil is a must for long lobe life. Valvoline VR1 or Red Line are good oils

Al, these are more like pits in the cyl. and yes I'm looking at the PAC 1409X springs, not sure which retainer yet. Been using Brad Penn oil.

Hows that #4 cap fit into the register? You probably should wet mag the crank.

Well I'm guessing it was the valve springs, or more so how they were set up, a stack of shims and no locator, the damper (with no locator) was bashing the shims and sending metal through the engine. I'm guessing some got through the filter. Also has the wrong retainers for the springs. Springs were pretty soft but hell maybe they are setup this way to loft the valve open or something with this square cam. One thing I didn't count on were the janky cylinders in the block, almost look rusted near the top of a few of them, we'll clean them up as good as we can... we gotta race.






I like to use a L31 Vortec retainer, with a -.050 tool steel keepers, and an Engine pro 1.250 cup locator with that set up. Light weight, simple and cheap, and it won't make metal, deburr the damper and spring ends.

Worked on cleaning some stuff today, chasing bolt holes and getting the heads cleaned and ready for a valve job and reassembly. I think we figured out the spring stuff needed. Gotta get a parts list started.
