ebay score! October 01, 2011, 02:57:34 AM just ordered a set of these for my 306.. good stuff, i've bought them before.. haven't seen them in a while, until tonight.. you just have to buy studs and push rod guides and you're good to go.. just sucks they don't have them in 1.7 ratio, but they have 3/8 and 7/16 (different auction) stud mount. most (if not all) factory ford heads are 5/16 - 18 thread, but you can buy studs with the 5/16 base thread and 3/8 on the rocker end.. or drill and tap your heads for 3/8 (or 7/16) studs.. says 'adds up to 30hp' but i don't think that's all that accurate, but they do free up some power lost from the friction of standard, non-roller rockershttp://www.ebay.com/itm/110700286928?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 Quote Selected

Reply #1 – October 01, 2011, 03:31:58 AM goodness gracious.. i keep finding more good dealsRHS / Pro Topline headshttp://cgi.ebay.com/ebaymotors/RHS-SBF-FORD-Aluminum-Heads-35001-Windsor-Bare-64cc-180cc-ProTopline-Mustang-/360397315295?pt=Motors_Car_Truck_Parts_Accessories&hash=item53e95a9cdfno-name cheapy aluminum heads, same specs as some name brand headshttp://cgi.ebay.com/ebaymotors/5-0-5-8-DIRECT-BOLT-PERFORMANCE-HEADS-SBF-FORD-ALUMINUM-BARE-PAIR-/290609654710?pt=Motors_Car_Truck_Parts_Accessories&hash=item43a9af6bb6ProComp heads.. i've installed a pair of these for a customer before, it's a good idea to take them to a machine shop to get them checked first.. they perform pretty well with a little port cleanup in the intake runners with a dual plane intake and gasket matching.. the motor i put them on dyno'd around 433hp with 9.8:1 compression and a decent little list of go-fast goodies, dyno'd at 394hp with a pair of decked and ported GT40p's, just to give you an idea.. pretty good gain for the pricehttp://cgi.ebay.com/ebaymotors/NEW-SBF-FORD-Aluminum-Cylinder-Heads-190cc-289-302-351W-/390300487226?pt=Motors_Car_Truck_Parts_Accessories&hash=item5adfb8ce3a Quote Selected
ebay score! Reply #2 – October 01, 2011, 07:14:52 AM I wonder how much more horse power the aluminum heads would actually give over my ported GT40-P heads. I know the difference in weight,but I'm more curious about the HP differences. Quote Selected
ebay score! Reply #3 – October 01, 2011, 09:15:19 AM would really depend on the combo.. but with some good cleaning of the ports, port matching the intake and stainless valves, you could see a decent increase Quote Selected
