Dallas TX Selling a set of #7a heads 64cc chambers. Already drilled for 403 head bolt size. Performance springs. Stock valve size. Perfect to bump up the pitiful smog compression in a 403
Came off a running motor. I purchased as is to use on my 403 build but ended up with a set of ported big valve #6 heads. Just looking to get my money back. $300 to a member here
