    I've recently come upon a chance to pick up a set of the MVA heads at a very reasonable price. I currently have the S&S 106 kit installed w/ the flat top pistons. Now, my question is, will my pistons work with these heads?? I have been looking for info on using the flat tops with these heads and I think I have just talked myself in circles. I think that if I use these heads I may take my compression down to approx. 9:1. (Closer to stock comp) Right now I'm sitting at about 10.5:1. These heads are milled for auto comp. releases, but at that low of a compression I think that they would be superfluous. Opinions??

    Well, as with any deal, opportunity, resources, timing and compatibility, besides the price are what drive the outcome...materials not so much.

    Try em, I have had experience with HTCC heads but have always used matching pistons, can't imagine what these MVA heads would do with flat tops, they are top of the line head and I have heard they like larger intakes and also like that 10.5 comp.
    I have broke away from rules putting high compression to low compression cams and had very happy engines, and you can read all you want on the internet but the fun part of anything is trying it, if it don't work, try, try, again, but then again there is something to be said for matching engine parts, have you done some research on maybe matching up some pistons? What heads are you running now?

    The price is great and I have the SE adjustable pushrods. I might just pull the trigger on this one.

    The SE catalog says that they are compatible with both types of pistons, the domed, and the flat tops. I might just do it and slap it on and head back to the dyno. This should be interesting... (And by slap it on I mean tear the whole thing down, clean it all up, put in new gaskets, readjust pushrods etc...) Thanks!!

    with flat top pistons,and 3.935 bore cylinders,you`ll be around 10.2-1,releaving the heads(or dishing the piston) to get to 9.1-1 woulndt be a big deal

    Yeah, I kind of feel the same way. The higher compression is a lot harder on many parts compared to just making the power with a bigger, badder, air and fuel flowing monster. I also like the lower compresssion b/c I think it's a more "streetable" machine and if you get a hold of some bad gas it's a lot more forgiving.

    a long with the mva heads would a cam say 258 in a 103 would this be a combo.worth investing in ?this would be a build on a 96" motor.
