i have 69 convertible 350 hp 350 serial #00003 built in sept 68. dont have original engine in it and trying to build one with correct casting numbers, need to know what heads this engine takes. been told 041 or 186 cant seem to find out which ones. thanks

My numbers book says casting # 3927187 valves 2.02/1.60 cc. 63.995

thanks for the info, now to try and find them.

It's a high performance head and may have been used on other applications, if possible try to get a casting date that precedes the build date on the trim tag.

hey mike check out this site. give them a call check there inventory.http://www.cranescorvette.com

Also get a Hemmings, there's a couple of vendors there that list castings.
