not sure about your situation but Pontiac stock heads won't take high lift cams, which sounds like what you have,, RAI & III style, 068 cam etc yes, but something like a RAII or IV, no, the factory used different heads with different springs, your push rods should be bent too if this is the case, Crane makes what they call Blueprint cams which are indentical to the factory, the 068 or 744 cams are great cams, the 041 which is the RAII & RAIV cam is too radical
it sounds like your top end has to come apart, sorry
Car has orig heads cast number 48..(350 H.O.). But when i get back to the car to replace the rest of the springs (Comp Cam 988-16) ill look for bent push rods... So will i be able to try 3/8 chevy rocker nuts on studs to adjust ???... I have a set of 7/16 studs and ball's and nuts but was unsure if the rocker balls will fit the stock rockers.
the 48 heads were originally made for the 350HO for the original Judge which never happened because DeLorean didn't want a 350 in a GTO, the heads then became the 400 RAIII available in the 69 year I believe, I'm not sure if you have a 350 or 400 based on this thread but I would check to be sure, a 350 would never take a big cam, neither would the 48 heads in a 350 or 400
verify what block you have, the 48 heads are great heads, take all of your pushrods out making sure to locate them where they came from, I use a drilled block of wood, roll each one on a plate of glass to see if any are bent and replace those, get the heads fixed, while the heads are off check the pistons for dents or worse, pop'er back together with a 068 cam
68, there was also a 350 "HO" which had increased power with the addition of higher compression #18 heads (#17 and #46 were the most common 2-barrel heads), a four-barrel carburetor and matching intake that was also used on the 400 and 428 engines. There was also the addition of dual exhaust, and in the case of a stick shift car, a slightly more aggressive cam.
In 1969 the 350 HO was upgraded again with the addition of the 400 HO cam, commonly referred to by Pontiac hobbyists as the 068 cam. Also added was the #48 casting number heads with a 68 cc (4.15 cu in) chamber for higher compression, along with larger 2.11 and 1.77 in (54 and 45 mm) valves. Free-flowing exhaust manifolds from the 400 RamAir were used late in the model year. This was underrated at 330 hp (246 kW). Many of GM's other divisions' 350's like Chevrolet, Buick and Oldsmobile and even the base SS396 were handily beaten by this little 350 "High Output" (HO) Pontiac.
Decode the production number and engine code. According to Pontiac Power, the production number for both 1968 and 1969 350 HO engines is #9790079. Between Pontiac Power and Firebird, the two-letter engine code is either "WK" or "WN.", in the first post it sounds like you do have a real 350HO, HOWEVER that engine is supposed to have the 068 cam, nothing else would be wise, these engines beat the hell out of chevy big blocks with the 068 cam, they flew, set it back to stock config, best of luck
