Seconary rod suggestion?

For those here, and to satisfy my own curiosity, I borrowed a gauge. At first I only got 185, then I remembered I didn't open the throttle! With that open it then read about 205. Quite frankly, I trust my gauge better. Oh, the engine was cold, I don't know how/if that affects the reading?

Pretty high pressure readings for 454 CID with a 230 @ .050" cam on a 110LSA. I'd suspect the true static compression is higher than you have calculated or the cam is advanced further than you think it is, or a little of both.......Cliff

Based on how the intake valve is poked out of the chamber. I would say those heads have been cut quite a bit. I found a pic of my 781's, but the files are to big to post. Mine dont poke out like in your pic. I also have the 2.19/1.85 valves and yours looks to be the original 2.09?

That is exactly what I've been hoping to hear, one way or the other. Since it isn't knocking, is there any drawback of having too high of a compression ratio? I have the timing at a modest 16* (for a BBC anyway). I know a lot of BB are set to 18 or 19.
73ss, I'm going to send you my email if you could share that picture with me please.?
