62...they are completely stock, only run on the car(Z06) for a few thousand miles.
-
stock 243's are 64.45 cc ....
-
I actually put that first, and then went and changed it. But they would be outside of your CC range unless you wanted to get them milled before installing.
-
ya, I don't want to pay 700 before any machining. I can get a set machined/built for about 1000
-
But will the ones that you get that are machined and built have the patriot dual springs with max lift of .660? if that's to high make an offer.
-
The price on the heads isn't terrible...it's just not what I need. Those will lower my compression to around a 9:1, so I will need to have them milled down, clearances checked, etc.
Brand new 59cc 5.3 heads are only 1200. I can have my stock heads worked for around the 700 (includes buying springs).
