Re: 454 BBC 781 heads
One of the best 'bang for the buck' bbc heads offered.
Mild port work & a good valve job & they'll flow as much as high dollar aftermarket heads. I don't recall typical compression ratios but I believe the 781's on my RetroRod combined w/a forged flat-top yielded 9.5:1. It will mainly depend on deck height, if the heads have been milled/surfaced, & what pistons are used.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
