    [SOLD] MT aluminum wrinkle black small block valve covers

    SOLD These came with some other parts. I am not a fan of wrinkle black and don't want to blast them to powder coat or paint them. They appear to be in very good condition save some oil soot on the inside, residual blue RTV & cork gasket remnants (see the new underside pics). Sadly, not as...

    I Chose the 383 Big Block

    IDK what your budget is but strongly consider hot tanking the block to clear out any gunk, new freeze plugs & reuse the threaded parts. I know you asked about a cam recommendation but what are your plans for the engine (daily driver, hot street, street/strip, strip, some of each, etc.)? I...

    I agree w/RRR. That piston is done. I'm surprised the cylinder wall survived. If this were me, I'd pull the other 7 pistons. Next, I'd put a mic on the cylinder walls with an eye to a rehone or possibly new +.020 slugs.

    Your considered opinion on heads please

    Thank you to all of you who have responded. The Speedmasters seem to be the overwhelming choice albeit a small sample size. I will also take @rumblefish360's advice and investigate bowl porting. I know I will be back with more questions and look forward to tapping into the considerable...

    Your considered opinion on heads please

    I appreciate the spring recommendation. Are we ok with the 10* Speedmaster spring retainers & valve locks or should we bulletproof it with corresponding Comp parts?

    I Chose the 383 Big Block

    My vote is to remove the piston & check the piston rings, piston skirt and cylinder wall on the right side where all the corrosion is located. I think you'll find there is a reason for the rings to be grabbing. I can't tell from the picture, but it appears the same corrosion is in the water...

    Your considered opinion on heads please

    That's good to hear, thanks. You said it 'was' really amazing. Are you using a different engine/cam now?
