heads

Was removed from a 1964 409 425HP restored engine to install period correct 583 Heads My 1964 Impala SS 409 425HP Dual Quad recently rebuilt engine was built with 690 heads. To make the engine correct for 1964 I replaced the 690 heads with correct 583 heads. Finding the 583 heads was difficult...

Hi, I recently purchased an early '58 348 passenger motor which needs some rebuilding (done by a qualified person) as I am not very knowledgeable with motors yet. However I am hoping to get some answers here on the forum regarding certain issues for my own personal knowledge. Thanks in advance...
