So I have decided to build my next engine. It will be a budget OG stroker - 400 block, 440 steel crank turned down to fit, Eagle H beam rods and Silvolite forged pistons. It will have a flat tappet solid cam in the .550 lift range and I would like to run it on pump premium as I drag and drive the car. I plan on 10.5: 1 to 11:1, the engine will go into my 49 Plymouth gasser. Hoping to put the car into the high to mid 11s.
My question is in regards to the heads. My back up plan is an old set of closed chamber big valve ported mid 60s heads that I have, however I am thinking an upgrade to new aluminum heads might be worthwhile.
From what I am seeing there are a few budget choices, but I am looking for real world experience on the Performance World 84210A (
Performance World 84210A BB Mopar 220cc Cylinder Heads Complete (pair)) or the 440 source stealth aluminum head (

Has anyone used either of these? Are there any other budget minded aluminum heads that will support my 451 stroker and are better than my 50 year old iron heads?
Thanks for any help!
As a side note, if anyone has a low deck performer RPM or street dominator intake they want to sell let me know!
