My engine was in the car when I bought it almost 20 yrs. ago. I have put 21,000+ miles on it. (total on engine 40,000+ miles). I've always had to add race fuel to the 94 octane and back down timing a couple of degrees to stop it from detonating.
With 93 octane, I need to add a little more race fuel. Since I retired, I drive the car a lot more. It's getting expensive.(1 gal of 116 oct. to <7 gals of 93 oct). I have asked a few local (smart) car guys about installing thicker head gaskets, like cometic .066 crushed.( felpro 8518PT are in it now). I am getting mixed answers, and "quench" was mentioned also. NOT sure what quench.
From my documentation book, I have a receipt from "G&R Performance" in Babylon, NY., 502 Rutgers Rd. Dated Oct. 1995. This is what's listed:
1- boiled block and installed cam bearings.
2- Milled the block. (I was told it was "0" decked)
3-bore and hone .030 over
4- polish and radius crank
5- clevite main bearings
6- balance assy.
7- miloden rod bolts
8-seal power rings
9- Lunati cam and lifters (230@50 dur. 460 lift).
10- boil and peen #77 heads. NOT ported, bronze guides, stock SS valves.
11- miloden screw in studs
12- heavy duty seal power springs
13- HS 1.5 roller rockers
14- I put on 65' tripower intake and correct carbs
15- stock exhaust manifolds and 2.5" Pypes "X" pipe system
Do you think the Cometic gaskets will help or make things worse???
thanks, Dave
