My SC is 11.4:1 with the GMPP 61cc heads using a stock gasket thickness. The car is tuned for 93 octane on motor,but I normally mix VP 109 and BP 93 at a 50/50 ratio due to the nitrous hit. If your going with TFS heads I'd use the 215's (64cc)...bigger is not always better when putting together the best combo.
I was thinking I always run bp93 and when I spray I was going to do the same like a 50/50 mix or 93 and 110 or jsut straight 100 when I spray..
What is a safe range of compression ratio to still run pump gas?

While I don't have a 383, (347), I do have an SCR of 12:1, and a DCR of about 9.3:1 - I run on 93 pump gas no problem. I'm a firm believer in getting the quench area as tight as possible. My AFR 205's are milled to 58cc, Cometic .051" gaskets, and the pistons are about .004" - .010" out of the hole IIRC. Compression is your friend.
