Thread: how do i remove valve cover to see ID engine numbers?

Yes it can be done.Small intake valve 350 heads work on a 307 or 305.
Not all 350 heads had the larger 1.94 intake valves.
I read your other thread about what a slow pig this thing is.
Regardless whether it's a 307 or 350, it can be tuned to run well as long as the internals are in good shape such as a good timing chain, good valve springs, good distributor, good camshaft with no flat lobes, etc.
It would help to get that casting number off of the back using a mirror to know where to start the correct tune on this thing.

ok.....good news

the block number is 3970010 and the suffix number is CHH

what do you think?

head number will get posted later today.
thanks
