Considering selling my S2’s to put the money into my S1 SE’s. Below is the info I know, they need work They are stage 2 SEs. The ports were raised and corrected with SRE spacers to .150 higher for a wildcat or spx raised runner. Ports and chambers need finish work. Bronze 11/32 valve guides and seats accept 2.160 intake , 1.75 exhaust. AMP port intruders and center 3 bolts have a steel sleeve done by Mike @ AMP. Port floors have been welded than machined to correct floor entry. $1400 for the bare heads and spacers. There is an outside chance I can get them to BG if prepaid. I need to check and see if my guy still has room. I am willing to ship, but it won’t be cheap. Local pickup in Clarks Summit PA 18411. More pics available upon request. Not listed elsewhere at this time.
