I would be looking for anything I can use for my new 545 build. I have a short block together. Thats where I stand. I can use tall valve covers, 10qt. oil pan, 850+cfm carb,etc... I have cash to throw on top of any item worth it... I also have pair of D3VE-A2A heads, not sure if I should use them or sell em. know anything about those heads?
