Agreed...but even if zero decked..that only takes maybe 15 to 20 thousandths out of equation..which is maybe 3 to 4 cc's...or 6 to 7 cc's remaining to mill to get the desired compression ratio. With that...you're still paying to have the block zero decked if not currently.. plus the additional expense of still having to mill 35 to 40 off the head and some off intake decks..which would still equate to $500 to get the heads to 9.5 to 1.

After reading what I posted...i realize I was being quite direct. Reason? I made that same mistake before and understood I spent $1200 more on the heads and could have achieved better performance by selling very rare and highly sought after #64 heads and went to 72 cc E heads only spending a little more for ARP bolts and gaskets.

Took me 6 years to find a buyer for modified heads I paid $1850 in 2000 for (cores, parts and labor) and took a $900 loss because they were limited in use to only 400 and not 428/455 builds..

I saw a marked increase in performance and handling with the 72 cc E heads...lower radiator temps..and could tell with a 3.55 rear...definite seat of pants feel in horsepower.
