Guest zfan Posted October 19, 2003 Share Posted October 19, 2003 Pete, You guy's have me scared shitless, I got my canfield heads from Competition Products and now I read they are crap! I am going to call Competition products and Canfield first thing monday as Canfield reps told me to buy my heads complete from them as they offer the best price/bang for your buck. I had mine cnc'd and upgraded to double roller springs good to .650 lift for my hydraulic roller cam: Comp cams 236/242-520/540 ls.110. If they hesitate at all I will refuse delivery and charge back to Comp. products and demand Canfield make it right for the same price. If they refuse then I will go AFR and let everyone know what went down. Crap I hope this is not the case..Fingers crossed. Grumpy! Have you heard any of this around your neck of the woods?

grumpyvette Posted October 19, 2003 Share Posted October 19, 2003 This is one of those cases, we'll have to check out the Canfield heads when you get them, I have seen many Canfield heads, that were in excellent condition right out of the box, but I always buy dirrect from canfield,yet I have heard, of several incidences where they were not in top condition. Wait until you get them, inspect them carefully, and if they are not to the condition you think they should be sent them back. In general. Canfield heads and I have seen have been very good condition, you can easily have been checked, and any good head porting shop with a flow bench. I think you find any major problems are obvious just by looking. In general I do not think you will have to worry about those heads being bad shape.

Pyro Posted October 21, 2003 Share Posted October 21, 2003 I'm not sure about the AFR's but I know the cantfelds will need +0.100 longer push rods which will cost another $100.00. Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted October 21, 2003 Share Posted October 21, 2003 just some EXTREMELY IMPORTANT INFO http://purplesagetradingpost.com/sumner/techinfo/heads1.html http://www.geocities.com/z28esser/headcomp.html http://www.dw1977.cz28.com/photo2.html http://www.canfieldheads.com/heads.html http://www.kendrick-auto.com/head_flow_figures.htm http://www.chevyhiperformance.com/techarticles/41598/ it's very hard for me to express strongly enough how important picking the correct cylinder heads and matching cam are to the results are likely to get from the engine, the best advice I can give you is to spend at least a third of your total budget on the cylinder heads and cam on any engine, a block and rotating assembly should also be approximately one third the cost of the total, the remaining third will be consumed in machine work costs, and parts like oil pans and intakes,etc. it. If you are not spending approximately that ratio you're unlikely to get the most out of the engine. Quote Link to comment Share on other sites More sharing options...
