360 heads

Well magnum heads will help compression and would be a step up over the stock teen head as far as breathing goes.There is a bit of extra hardware to convert but its not bad.

400 hp is easily acheivable without porting.

Any 360 head you buy will have large open combustion chambers and the comp will drop to about 7.5:1 unless they are cut to reduce chamber size

The new rhs heads are good.Msgnum chambers and shaft rockers for the best of both generations. Contact OU812,he is the dealer on this sight.
